The DWARF-4 specification added 2 new fields in the CIE header called
address_size and segment_size.
Create these 2 new fields when generating dwarf-4 CIE entries, print out
the new fields when dumping the CIE and update tests

Specifically, this patch correctly respects the -demangle option,
and additionally adds a hidden --relative-address option allows
input addresses to be relative to the module load address instead
of absolute addresses into the image.

This patch adds the --load-address command line option to
llvm-pdbdump, which dumps all addresses assuming the module has
loaded at the specified address.
Additionally, this patch adds an option to llvm-pdbdump to support
dumping of public symbols (i.e. symbols with external linkage).

PDB uses COFFObjectFile::getPE32Header which lives in libObject.
Make sure that LLVMBuild.txt reflects this dependency.

Previously DebugInfoPDB could only load data for a PDB given a
path to the PDB. It could not open an EXE and find the matching
PDB and verify it matched, etc. This patch adds support for that
so that we can simply load debug information for a PDB directly.
Additionally, this patch extends DebugInfoPDB to support getting
source and line information for symbols.

The implementation accepts explicitely signed forms (DW_FORM_sdata),
but also unsigned forms as long as they fit in an int64_t.

This will now display enum definitions both at the global
scope as well as nested inside of classes. Additionally,
it will no longer display enums at the global scope if the
enum is nested. Instead, it will omit the definition of
the enum globally and instead emit it in the corresponding
class definition.

A short list of some of the improvements:
1) Now supports -all command line argument, which implies many
other command line arguments to simplify usage.
2) Now supports -no-compiler-generated command line argument to
exclude compiler generated types.
3) Prints base class list.
4) -class-definitions implies -types.
5) Proper display of bitfields.
6) Can now distinguish between struct/class/interface/union.
And a few other minor tweaks.

Previously it was impossible to distinguish between "There is
no PDB implementation for this platform" and "I tried to load
the PDB, but couldn't find the file", making it hard to figure
out if you built llvm-pdbdump incorrectly or if you just mistyped
a file name.
This patch adds proper error handling so that we can know exactly
what went wrong.

All of the cases were just appending from random access iterators to a
vector. Using insert/append can grow the vector to the perfect size
directly and moves the growing out of the loop. No intended functionalty
change.

Function pointers were not correctly handled by the dumper, and
they would print as "* name". They now print as
"int (__cdecl *name)(int arg1, int arg2)" as they should.
Also, doubles were being printed as floats. This fixes that bug
as well, and adds tests for all builtin types. as well as a test
for function pointers.

Move the FrameEntry::dumpInstructions down in the file at some
place where it can see the declarations of FDE and CIE.

This is the first commit in a small series aiming at making
debug_frame dump more useful (right now it prints a list of
opeartions without their operands).

This reverts commit r230062.
Debian stable (wheezy) ships still with cmake 2.8.9.
The commit broke my LLVM/Polly buildbot, to my knowledge our only Linux+cmake
buildbot.

This adds the --class-definitions flag. If specified, when dumping
types, instead of "class Foo" you will see the full class definition,
with member functions, constructors, access specifiers.
NOTE: Using this option can be very slow, as generating a full class
definition requires accessing many different parts of the PDB.

This increases the flexibility of how to dump different
symbol types -- necessary for context-sensitive formatting of
symbol types -- and also improves the modularity by allowing
the dumping to be implemented in the actual dumper, as opposed
to in the PDB library.

This removes a wealth of options, and instead now only provides
three options. -symbols, -types, and -compilands. This greatly
simplifies use of the tool, and makes it easier to understand
what you're going to see when you run the tool.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@230182 91177308-0d34-0410-b5e6-96231b3b80d8
Dumping the global scope contains a lot of very uninteresting
things and is generally polluted with a lot of random junk.
Furthermore, it dumps values unsorted, making it hard to read.
This patch dumps known interesting types only, and as a side
effect sorts the list by symbol type.

This correctly prints the function pointers, and also prints
function signatures for symbols as opposed to just types. So
actual functions in your program will now be printed with full
name and signature, as opposed to just name as before.

In particular this patch adds the ability to dump complete
function signature information including argument types as
correctly formatted strings. A side effect of this is that
almost all symbol and meta types are now formatted.

This patch adds a number of improvements to llvm-pdbdump.
1) Dumping of the entire global scope, and not only those
symbols that live in individual compilands.
2) Prepend class name to member functions and data
3) Improved display of bitfields.
4) Support for dumping more kinds of data symbols.
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@229012 91177308-0d34-0410-b5e6-96231b3b80d8
Frequently you only want to iterate over children of a specific
type (e.g. functions). Previously you would get back a generic
interface that allowed iteration over the base symbol type,
which you would have to dyn_cast<> each one of. With this patch,
we allow the user to specify the concrete type as a template
parameter, and it will return an iterator which returns instances
of the concrete type directly.

This makes llvm-pdbdump available on all platforms, although it
will currently fail to create a dumper if there is no PDB reader
implementation for the current platform.
It implements dumping of compilands and children, which is less
information than was previously available, but it has to be
rewritten from scratch using the new set of interfaces, so the
rest of the functionality will be added back in subsequent commits.

This implements DebugInfoPDB when the DIA SDK is present on the system.
Specifically, this means that the following conditions are met:
1) You are building on Windows.
2) You are building with MSVC.
3) Visual Studio did not corrupt the installation of DIA due to a
known issue with side-by-side installations of VS2012 and VS2013.
If all of these conditions are true, you will be able to pass a value
of PDB_Reader::DIA to PDB::createPdbReader().
There are no tests for this yet, as any test will be in the form of a
lit test which tests the llvm-pdbdump.exe, which still needs to be
rewritten in terms of this library.
