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.

Craig Topper f1c2016075 Separate AVXCC and SSECC printing for cmpps/pd/ss/sd and add masking before the switch statement. This keeps the unreachable default case from being hit if the instruction was created with an intrinsic with too large of an immediate.

Michael Liao 425c0dbc81 Add 'lock' prefix output support in assembly printer 
- Instead of embedding 'lock' into each mnemonic of atomic
  instructions except 'xchg', we teach X86 assembly printer to output 'lock'
  prefix similar to or consistent with code emitter.

Benjamin Kramer 1c0541b031 Move getOpcodeName from the various target InstPrinters into the superclass MCInstPrinter. 
All implementations used the same code.

Craig Topper dab9e35ad0 Remove getInstructionName from MCInstPrinter implementations in favor of using the instruction name table from MCInstrInfo. Reduces static data in the InstPrinter implementations.

Benjamin Kramer 682de39f2d Rip out emission of the regIsInRegClass function for the asm printer. 
It's slow, bloated and completely redundant with MCRegisterClass::contains.

Jim Grosbach fd93a59557 Make MCRegisterInfo available to the the MCInstPrinter. 
Used to allow context sensitive printing of super-register or sub-register
references.

Kevin Enderby 6fbcd8d439 Updated the llvm-mc disassembler C API to support for the X86 target. 
rdar://10873652

As part of this I updated the llvm-mc disassembler C API to always call the
SymbolLookUp call back even if there is no getOpInfo call back.  If there is a
getOpInfo call back that is tried first and then if that gets no information
then the  SymbolLookUp is called.  I also made the code more robust by
memset(3)'ing to zero the LLVMOpInfo1 struct before then setting
SymbolicOp.Value before for the call to getOpInfo.  And also don't use any
values from the  LLVMOpInfo1 struct if getOpInfo returns 0.  And also don't
use any of the ReferenceType or ReferenceName values from SymbolLookUp if it
returns NULL. rdar://10873563 and rdar://10873683

For the X86 target also fixed bugs so the annotations get printed. 

Also fixed a few places in the ARM target that was not producing symbolic
operands for some instructions.  rdar://10878166

I added the full testing for all possible pseudo-ops of cmp.
I extended X86AsmPrinter.cpp and X86IntelInstPrinter.cpp.

You'l also see lines alignments (unrelated to this fix) in X86IselLowering.cpp from my previous check-in.

Owen Anderson a0c3b97221 Don't attach annotations to MCInst's. Instead, have the disassembler return, and the printer accept, an annotation string which can be passed through if the client cares about annotations.

true on success and false on failure. Update callers.

Bill Wendling 7e07d6fb69 Have the X86 back-end emit the alias instead of what's being aliased. In most 
cases, it's much nicer and more informative reading the alias.

Bill Wendling bc3f79044a Replace the old algorithm that emitted the "print the alias for an instruction" 
with the newer, cleaner model. It uses the IAPrinter class to hold the
information that is needed to match an instruction with its alias. This also
takes into account the available features of the platform.

There is one bit of ugliness. The way the logic determines if a pattern is
unique is O(N**2), which is gross. But in reality, the number of items it's
checking against isn't large. So while it's N**2, it shouldn't be a massive time
sink.

Jim Grosbach 0e854f3d43 Rename the AsmPrinter directory to InstPrinter for those targets that have 
been MC-ized for assembly printing. MSP430 is mostly so, but still has the
asm printer and lowering code in the printer subdir for the moment.
