Rafael Espindola 5dce65b21e Give each MCCFIInstruction its own opcode.
This untangles the switch cases of the old Move and RelMove opcodes a bit
and makes it clear how to add new instructions.

Rafael Espindola 1c3086cc91 Refactor how MCCFIInstructions are created.
Give MCCFIInstruction a single, private constructor and add helper static
methods that create each type of cfi instruction. This is is preparation
for changing its representation. The representation with a pair
MachineLocations older than MC and has been abused quiet a bit to support
more cfi instructions.

Adhemerval Zanella f2aceda854 Initial TOC support for PowerPC64 object creation
This patch adds initial PPC64 TOC MC object creation using the small mcmodel
(a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC,
R_PPC64_TOC16, and R_PPC64_TOC16DS).

The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter'
is meant to avoid the creation of an unreferenced ".TOC." symbol (used in
the .odp creation) as well to set the R_PPC64_TOC relocation target as the
temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should
not point to any symbol.

Chad Rosier 91c8266200 [ms-inline asm] Create a register operand, rather than a memory operand when we
see the offsetof operator.  Previously, we were matching something like MOVrm
in the front-end and later matching MOVrr in the back-end.  This change makes
things more consistent.  It also fixes cases where we can't match against a 
memory operand as the source (test cases coming).

Kevin Enderby 62183c4e18 Add support for annotated disassembly output for X86 and arm.
Per the October 12, 2012 Proposal for annotated disassembly output sent out by
Jim Grosbach this set of changes implements this for X86 and arm.  The llvm-mc
tool now has a -mdis option to produced the marked up disassembly and a couple
of small example test cases have been added.

Chad Rosier 8bce664144 [ms-inline asm] Move most of the AsmParsing logic in clang back into the MC
layer.  Add the ParseMSInlineAsm() function, which is the new interface to 
clang.  Also expose the new MCAsmParserSemaCallback interface, which is used
by the back-end to do name lookup in Sema.  Finally, remove the now defunct
APIs introduced in r165946.

Chad Rosier 0d6f149e62 [ms-inline asm] Add a few new APIs to the AsmParser class in support of MS-Style
inline assembly.  For the time being, these will be called directly by clang.
However, in the near future I expect these to be sunk back into the MC layer
and more basic APIs (e.g., getClobbers(), getConstraints(), etc.) will be called
by clang.

Chad Rosier 4996355592 [ms-inline asm] Remove the MatchInstruction() function. Previously, this was
the interface between the front-end and the MC layer when parsing inline
assembly.  Unfortunately, this is too deep into the parsing stack. Specifically,
we're unable to handle target-independent assembly (i.e., assembly directives,
labels, etc.).  Note the MatchAndEmitInstruction() isn't the correct
abstraction either.  I'll be exposing target-independent hooks shortly, so this
is really just a cleanup.
