Kevin Enderby 8be42bd09f 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.

Kevin Enderby 644de27659 Fix ARM memory operand parsing of post indexing with just a base register, that
is just "[Rn]" and no tailing comma with an offset, etc.

Kevin Enderby 146dcf2ab5 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.

Kevin Enderby f50799412c 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.

Kevin Enderby 3f0b9b3db4 Fix a problem in the code where ARMAsmParser::ParseShift() second argument
should have been a pointer to a reference.

Kevin Enderby a2b99107c4 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.

Kevin Enderby 2207e5fc7b 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.

Kevin Enderby febe39b488 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.

Kevin Enderby ccab317837 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.
