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.

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.

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.

Also fixed a couple of coding style things that crept in.  And added more
to the temporary hacked up ARMAsmParser::MatchInstruction() method for testing.

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.

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.

operands.  Some parsing of arm memory operands for preindexing and postindexing
forms including with register controled shifts.  This is a work in progress.

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.
