-The front-end now builds a single assembly string and feeds it to the
 AsmParser.  The front-end iterates on a per statement basis by calling the
 ParseStatement() function.  Please note, the calling of ParseStatement() and
 and any notion of MCAsmParsedOperands will be sunk into the MC layer in the
 near future.  I plan to expose more basic APIs such as getClobbers, etc.

-The enumeration of the AsmString expressions have been reworked to use SMLocs
 rather than assembly Pieces, which were being parsed in the front-end.

-The test case, t8(), was modified due to r129223.  I'll have to find a way to
 work around things such as these.

Sorry for the large commit, but breaking this in multiple smaller commits proved
too irritating.

The test case needs to be remove temporarily until I can better filter memory
operands that aren't actual variable reference.

more robust way to address a few FIXMEs.

The initial implementation, r163342, built the IR asm string and then tried to
patch things on the fly without enough context.  Specifically, it didn't skip
mnemonics nor did it track with assembly instruction an expression was related
to.  The new implementation patches the operands and then builds the final
IR string.

MCOperands then iterate over all of then when computing clobbers, inputs and
outputs.

On x86 the 1-to-many mapping is a memory operand that includes a BaseReg(reg),
MemScale(imm), MemIndexReg(reg), an Expr(MCExpr or imm) and a MemSegReg(reg).
Invalid register (Op.getReg() == 0) are not considered when computing clobber.
