17feeec8d8 [ms-inline asm] If the state of the parser is ignore, then don't parse the
inline assembly.  Also make sure the remove the ignored statements from the IR.

c8dd27e583 [ms-inline asm] Have the LookupInlineAsmIdentifier() callback function return a
*NamedDecl.  In turn, build the expressions after we're finished parsing the
asm.  This avoids a crasher if the lookup fails.

b1f8c139c5 [ms-inline asm] Move most of the AsmParsing logic in clang back into the MC
layer.  Add the ParseMSInlineAsm() function, which is the new interface to 
clang.  Also expose the new MCAsmParserSemaCallback interface, which is used
by the back-end to do name lookup in Sema.  Finally, remove the now defunct
APIs introduced in r165946.

8f138d1121 [ms-inline asm] Add a few new APIs to the AsmParser class in support of MS-Style
inline assembly.  For the time being, these will be called directly by clang.
However, in the near future I expect these to be sunk back into the MC layer
and more basic APIs (e.g., getClobbers(), getConstraints(), etc.) will be called
by clang.

84125ca43c [ms-inline asm] Remove the MatchInstruction() function. Previously, this was
the interface between the front-end and the MC layer when parsing inline
assembly.  Unfortunately, this is too deep into the parsing stack. Specifically,
we're unable to handle target-independent assembly (i.e., assembly directives,
labels, etc.).  Note the MatchAndEmitInstruction() isn't the correct
abstraction either.  I'll be exposing target-independent hooks shortly, so this
is really just a cleanup.
