2eca0252c3 llvm-mc: Add -show-inst-operands, for dumping the parsed instruction representation before matching.

a3e0ddb564 Plug the remaining MC leaks by giving MCObjectStreamer/MCAsmStreamer ownership of the TargetAsmBackend and the MCCodeEmitter.

419197cc4d Target: Give the TargetAsmParser access to the TargetMachine. 
- Unfortunate, but necessary for now to handle subtarget instruction matching. Eventually we should factor out the lower level target machine information so we don't need to do this.

638cdb2db1 Currently, createMachOStreamer() is invoked directly in llvm-mc which 
isn't ideal if we want to be able to use another object file format.

Add a createObjectStreamer() factory method so that the correct object
file streamer can be instantiated for a given target triple.

2d03d3a8a7 Second try at integrating the edis tester. This 
time I use the LIBS variable, which is not subject
to a %.a -> -l% transformation, to link llvm-mc
against libEnhancedDisassembly.

llvm-mc -edis works the same as llvm-mc
-disassemble, but outputs tokens and operands.

7012916275 fix an ugly wart in the MCInstPrinter api where the 
raw_ostream to print an instruction to had to be specified
at MCInstPrinter construction time instead of being able
to pick at each call to printInstruction.

d821f4ac60 llvm-mc: Add a -mc-relax-all option, which relaxes every fixup. We always need 
exactly two passes in that case, and don't ever need to recompute any layout,
so this is a nice baseline for relaxation performance.

SourceMgr.

177934e021 Changed the AsmParser to handle error messages itself 
rather than passing them off to the AsmLexer to handle.
This means the AsmLexer no longer requires a SourceMgr
to do error handling.

7e64550747 Test harness for the LLVM disassembler. When invoked 
with -disassemble, llvm-mc now accepts lines of the
form
0x00 0x00
and passes the resulting bytes to the disassembler for
the chosen (or default) target, printing the result.

11b2fc9ea4 Change MCAsmStreamer to take an MCInstPrinter instead of a 
full AsmPrinter, and change TargetRegistry to keep track
of registered MCInstPrinters.

llvm-mc is still linking in the entire
target foo to get the code emitter stuff, but this is an
important step in the right direction.

ce4bec8e0c Added the ParseInstruction() hook for target specific assembler directives so 
that things like .word can be parsed as target specific.  Moved parsing .word
out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes
for other targets that support the .word directive.

f92f9909c4 Added the AsmToken::Hash enum constant to MCAsmLexer.h in preparation of 
supporting other targets.  Changed the code to pass MCAsmInfo to the parser
and the lexer.  Then changed the lexer to use CommentString from MCAsmInfo
instead of a literal '#' character.

7d91218c75 Removed the non-target independent AsmToken::Register enum constant 
from MCAsmLexer.h in preparation of supporting other targets.  Changed the
X86AsmParser code to reflect this by removing AsmLexer::LexPercent and looking
for AsmToken::Percent when parsing in places that used AsmToken::Register.
Then changed X86ATTAsmParser::ParseRegister to parse out registers as an
AsmToken::Percent followed by an AsmToken::Identifier.
