[ms-inline asm] Address the FIXME in AsmParser.cpp.

Browse Source 
// FIXME: Constraints are hard coded to 'm', but we need an 'r'
// constraint for addressof.  This needs to be cleaned up!

Test cases are already in place.  Specifically,
clang/test/CodeGen/ms-inline-asm.c t15(), t16(), and t24().
