0d50598d71 Pass a unique_ptr<MemoryBuffer> to the constructors in the Binary hierarchy.
Once the objects are constructed, they own the buffer. Passing a unique_ptr
makes that clear.

b138caba43 Pass a std::unique_ptr& to the create??? methods is lib/Object.
This makes the buffer ownership on error conditions very natural. The buffer
is only moved out of the argument if an object is constructed that now
owns the buffer.

1f659329b6 Make ObjectFile and BitcodeReader always own the MemoryBuffer.
This allows us to just use a std::unique_ptr to store the pointer to the buffer.
The flip side is that they have to support releasing the buffer back to the
caller.

Overall this looks like a more efficient and less brittle api.

138222e56f Change the default input for llvm-nm to be a.out instead of standard input
to match llvm-size and other UNIX systems for their nm(1).

Tweak test cases that used llvm-nm with standard input to add a "-" to
indicate that and add a test case to check the default of a.out for llvm-nm.

2ae686a2ab The gold plugin doesn't need disassemblers.
Back in r128440 tools/LTO started exporting the disassembler interface. It
was never clear why, but whatever the reason I am pretty sure it doesn't hold
for tools/gold.

fat files) to print “ (for architecture XYZ)” for fat files with more than

0b5745abd8 Use lib/LTO directly in the gold plugin.
The tools/lto API is not the best choice for implementing a gold plugin. Among
other issues:

* It is an stable ABI. Old errors stay and we have to be really careful
  before adding new features.
* It has to support two fairly different linkers: gold and ld64.
* We end up with a plugin that depends on a shared lib, something quiet
  unusual in LLVM land.
* It hides LLVM. For some features in the gold plugin it would be really
  nice to be able to just get a Module or a GlobalValue.

This change is intended to be a very direct translation from the C API. It
will just enable other fixes and cleanups.

Tested with a LTO bootstrap on linux.

acc5e810aa Add "-format darwin" to llvm-size to be like darwin's size(1) -m output, and
and the -l option for the long format.  Also when the object is a Mach-O
file and the format is berkeley produce output like darwin’s default size(1)
summary berkeley derived output.

Like System V format, there are also some small changes in how and where
the file names and archive member names are printed for darwin and
Mach-O.

Like the changes to llvm-nm these are the first steps in seeing if it is
possible to make llvm-size produce the same output as darwin's size(1).

d8b23109b2 Finishing touch for the std::error_code transition.
While std::error_code itself seems to work OK in all platforms, there
are few annoying differences with regards to the std::errc enumeration.

This patch adds a simple llvm enumeration, which will hopefully avoid build
breakages in other platforms and surprises as we get more uses of
std::error_code.

df46288714 opt: Initialize asm printers
Without initializing the assembly printers a shared library build of opt is
linked with these libraries whereas for a static build these libraries are dead
code eliminated. This is unfortunate for plugins in case they want to use them,
as they neither can rely on opt to provide this functionality nor can they link
the printers in themselves as this breaks with a shared object build of opt.

This patch calls InitializeAllAsmPrinters() from opt, which increases the static
binary size from 50MB -> 52MB on my system (all backends compiled) and causes no
measurable increase in the time needed to run 'make check'.

7acd886ecf Use std::error_code instead of llvm::error_code.
The idea of this patch is to turn llvm/Support/system_error.h into a
transitional header that just brings in the erorr_code api to the llvm
namespace. I will remove it shortly afterwards.

The cases where the general idea needed some tweaking:

* std::errc is a namespace in msvc, so we cannot use "using std::errc". I could
add an #ifdef, but there were not that many uses, so I just added std:: to
them in this patch.

* Template specialization had to be moved to the std namespace in this
patch set already.

* The msvc implementation of default_error_condition doesn't seem to
provide the same transformations as we need. Not too surprising since
the standard doesn't actually say what "equivalent" means. I fixed the
problem by keeping our old mapping and using it at error_code
construction time.

Despite these shortcomings I think this is still a good thing. Some reasons:

* The different implementations of system_error might improve over time.
* It removes 925 lines of code from llvm already.
* It removes 6313 bytes from the text segment of the clang binary when
it is built with gcc and 2816 bytes when building with clang and
libstdc++.

3ddcc49650 tools: add a high level explanation for WoA EH data
Add a brief explanation of the data section layout for the unwind data that the
Windows on ARM EH models.  This is simply to provide a rough idea of the layout
of the code involved in the decoding of the unwinding.  Details on the involved
data structures are available in the associated support header.  The bulk of it
is related to printing out the byte-code to help validate generation of WoA EH.

ecbc72405e Add "-format darwin" to llvm-nm to be like darwin's nm(1) -m output.
This is a first step in seeing if it is possible to make llvm-nm produce
the same output as darwin's nm(1).  Darwin's default format is bsd but its
-m output prints the longer Mach-O specific details.  For now I added the
"-format darwin" to do this (whos name may need to change in the future).
As there are other Mach-O specific flags to nm(1) which I'm hoping to add some
how in the future.  But I wanted to see if I could get the correct output for
-m flag using llvm-nm and the libObject interfaces.

fe3b74ec71 tools: initial implementation of WoA EH decoding
Add support to llvm-readobj to decode Windows ARM Exception Handling data.  This
uses the previously added datastructures to decode the information into a format
that can be used by tests.  This is a necessary step to add support for emitting
Windows on ARM exception handling information.

A fair amount of formatting inspiration is drawn from the Win64 EH printer as
well as the ARM EHABI printer.  This allows for a reasonably thorough look into
the encoded data.

2d21b25393 Allow alias to point to an arbitrary ConstantExpr.
This  patch changes GlobalAlias to point to an arbitrary ConstantExpr and it is
up to MC (or the system assembler) to decide if that expression is valid or not.

This reduces our ability to diagnose invalid uses and how early we can spot
them, but it also lets us do things like

@test5 = alias inttoptr(i32 sub (i32 ptrtoint (i32* @test2 to i32),
                                 i32 ptrtoint (i32* @bar to i32)) to i32*)

An important implication of this patch is that the notion of aliased global
doesn't exist any more. The alias has to encode the information needed to
access it in its metadata (linkage, visibility, type, etc).

Another consequence to notice is that getSection has to return a "const char *".
It could return a NullTerminatedStringRef if there was such a thing, but when
that was proposed the decision was to just uses "const char*" for that.

19ab8f850f [yaml2obj][ELF] Add an optional Size field to the YAML section declaration.
Now the only method to configure ELF section's content and size is to assign
a hexadecimal string to the `Content` field. Unfortunately this way is
completely useless when you need to declare a really large section.

To solve this problem this patch adds one more optional field `Size`
to the `RawContentSection` structure. When yaml2obj generates an ELF file
it uses the following algorithm:
1. If both `Content` and `Size` fields are missed create an empty section.
2. If only `Content` field is missed take section length from the `Size`
   field and fill the section by zero.
3. If only `Size` field is missed create a section using data from
   the `Content` field.
4. If both `Content` and `Size` fields are provided validate that the `Size`
   value is not less than size of `Content` data. Than take section length
   from the `Size`, fill beginning of the section by `Content` and the rest
   by zero.

Examples
--------
* Create a section 0x10000 bytes long filled by zero
  Name: .data
  Type: SHT_PROGBITS
  Flags: [ SHF_ALLOC ]
  Size: 0x10000

* Create a section 0x10000 bytes long starting from 'CA' 'FE' 'BA' 'BE'
  Name: .data
  Type: SHT_PROGBITS
  Flags: [ SHF_ALLOC ]
  Content: CAFEBABE
  Size: 0x10000

ae417592a5 Fix llvm-nm to print the full 64-bit address for symbols in 64-bit object files.
The implementation might be better to have a method is64Bit() in the class
SymbolicFile instead of having the static routine isSymbolList64Bit() in
llvm-nm.cpp .  But this is very much in the sprit of isObject() and
getNMTypeChar() in llvm-nm.cpp that has a series of if else statements
based on the specific class of the SymbolicFile.  I can update this if
folks would like.

Also the tests were updated to be explicit about checking the address for
64-bits or 32-bits from object files.
