f230df9af4 Add a MCObjectFormat class so that code common to all targets that use a 
single object format can be shared.

This also adds support for

mov zed+(bar-foo), %eax

8f413fa9c0 On ELF we need to know which symbols are used in relocations to decide if 
they should be in the symbol table or not. Instead of "guessing", just compute
the symbol table after the relocations are known.

3f55c24df9 Incorporate suggestions by Daniel Dunbar after his review. Thanks Daniel! 
1) Changed ValidateDwarfFileNumber() to isValidDwarfFileNumber() to be better
   named.  Since it is just a predicate and isn't actually changing any state.

2) Added a missing return in the comments for setCurrentDwarfLoc() in 
   include/llvm/MC/MCContext.h for fix formatting.

3) Changed clearDwarfLocSeen() to ClearDwarfLocSeen() since it does change
   state.

4) Simplified the last test in isValidDwarfFileNumber() to just a one line
   boolean test of MCDwarfFiles[FileNumber] != 0 for the final return statement.

7070387f08 Make it possible for the MCObjectWriter to decide if a given fixup is fully 
resolved or not. Different object files have different restrictions and
different native assemblers have different idiosyncrasies we want to emulate
for now.

Move the existing MachO logic to the new place and implement an ELF one that
gets fixups to globals right.

637d89fe0e Add support for ELF PLT references for ARM MC asm printing. Adding a 
new VariantKind to the MCSymbolExpr seems like overkill, but I'm not sure
there's a more straightforward way to get the printing difference captured.
(i.e., x86 uses @PLT, ARM uses (PLT)).

d80781b98b Add a InitSections method to the streamer interface. 
The ELF implementation now creates text, data and bss to match the gnu as
behavior.

The text streamer still has the old MachO specific behavior since
the testsuite checks that it will error when a directive is given
before a setting the current section for example.

A nice benefit is that -n is not required anymore when producing
ELF files.

26edbcb8d5 Add support for floating point immediates to MC instruction printing. ARM 
VFP instructions use it for loading some constants, so implement that
handling.

Not thrilled with adding a member to MCOperand, but not sure there's much of
a better option that's not pretty fragile (like putting a double in the
union instead and just assuming that's good enough). Suggestions welcome...

cbf8a98c7c fix the asmparser so that the target is responsible for skipping to 
the end of the line on a parser error, allowing skipping to happen
for syntactic errors but not for semantic errors.  Before we would
miss emitting a diagnostic about the second line, because we skipped
it due to the semantic error on the first line:

  foo %eax
  bar %al

This fixes rdar://8414033 - llvm-mc ignores lines after an invalid instruction mnemonic errors

232ab949d5 This is the second of three patches to implement support for the .loc directive 
and output the dwarf line number tables.  This takes the current loc info after
an instruction is assembled and saves the needed info into an object that has
vector and for each section.  These objects will be used for the final patch to 
build and emit the encoded dwarf line number tables.  Again for now this is only
in the Mach-O streamer but at some point will move to a more generic place.

instruction is assembled and save that info into a vector for each section for
use to build the line number tables.  The patch after that will encode the info
from those vectors into the output file as the dwarf line tables.

7cbf73a73f Added first bit of support for the dwarf .file directive. This patch collects 
the info from the .file directive and makes file and directory tables that
will eventually be put out as part of the dwarf info in the output file.

.weak_def_can_be_hidden directive.  Chris pointed out that the MCAsmInfo.h/.cpp
chunks aren't needed for this until the compiler starts generating these.  And
when that happens it will be more convenient for it to be a bool than a const
char*.

207855cff9 Introducing the "linker_weak" linkage type. This will be used for Objective-C 
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".
