Marina Yatsina 477847f6ac [X86] MS inline asm: produce error when encountering "<type> ptr <reg name>"
Currently "<type> ptr <reg name>" treated as <reg name> in MS inline asm, ignoring the "<type> ptr" completely and possibly ignoring the intention of the user.
Fixed llvm to produce an error when encountering "<type> ptr <reg name>" operands.

For example: andpd xmm1,xmmword ptr xmm1 --> andpd xmm1, xmm1 
though andpd has 2 possible matching formats - andpd xmm, xmm/m128
