9898671a74 Split the TargetAsmParser "ParseInstruction" interface in half:
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to
turn the operand list into an MCInst.

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.

f007e853e2 prune #includes in TargetAsmParser.h
Pass in SMLoc of instr opcode into ParseInstruction.
Make AsmToken be a class, not a struct.

079b6f5ee5 Add an "ATTRIBUTE_UNUSED" macro (and use it). It's for variables which are
mainly used in debugging and/or assert situations. It should make the compiler
and the static analyzer stop nagging us about them.

9c41fa87ea Updates to the ARM target assembler for llvm-mc per review comments from
Daniel Dunbar.
- Reordered the fields in the ARMOperand Mem struct to make the struct smaller.
Making bool's into 1 bit fields and put the MCExpr* fields adjacent to each
other.
- Fixed a number of places in ARMAsmParser.cpp so they have doxygen comments.
- Change the name of ARMAsmParser::ParseRegister() to MaybeParseRegister and
added the bool ParseWriteBack parameter.
- Changed ARMAsmParser::ParseMemory() to call MaybeParseRegister().
- Added ARMAsmParser::ParseMemoryOffsetReg to factor out parsing the offset of a
memory operand.  And use it for both parsing both preindexed and post indexing
addressing forms in ARMAsmParser::ParseMemory.
- Changed the first argument to ParseShift() to a reference.
- Changed ParseShift() to check for Rrx first and return to reduce nesting.

is just "[Rn]" and no tailing comma with an offset, etc.

515d509360 More bits of the ARM target assembler for llvm-mc, code added to parse labels
as expressions, code for parsing a few arm specific directives (still needs
the MCStreamer calls for these).  Some clean up of the operand parsing code
and adding some comments.

cfe0724016 More bits of the ARM target assembler for llvm-mc to parse immediates.
Also fixed a couple of coding style things that crept in.  And added more
to the temporary hacked up ARMAsmParser::MatchInstruction() method for testing.

d7894f105a Added another bit of the ARM target assembler to llvm-mc to parse register
lists.  Changed ARMAsmParser::MatchRegisterName to return -1 instead of 0 on
errors so 0-15 values could be returned as register numbers.  Also added the
rest of the arm register names to the currently hacked up version to allow more
testing.  Some changes to ARMAsmParser::ParseOperand to give different errors
for things not yet supported and some additions to the hacked
ARMAsmParser::MatchInstruction to allow more testing for now.

99e6d4e839 Add another bit of the ARM target assembler to llvm-mc to parse registers
with writeback, things like "sp!", etc.  Also added some more stuff to the
temporarily hacked methods ARMAsmParser::MatchRegisterName and
ARMAsmParser::MatchInstruction to allow more parser testing.

a7ba3a81c0 Added bits of the ARM target assembler to llvm-mc to parse some load instruction
operands.  Some parsing of arm memory operands for preindexing and postindexing
forms including with register controled shifts.  This is a work in progress.

ca9c42c4da Added the first bits of the ARM target assembler to llvm-mc. For now it only
parses the .word directive as 4 bytes and ARMAsmParser::ParseInstruction will
give an error is called.  Broke out the test of the .word directive into two
different test cases, one for x86 and one for arm.
