[ms-inline asm] Rework the front-end to use the API introduced in r165946.
...
-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 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.

Invalid register (Op.getReg() == 0) are not considered when computing clobber.

and
