Reid Kleckner 6d2ea6ec80 [ms-inline-asm] Use the frontend size only for ambiguous instructions 
This avoids problems on code like this:
  char buf[16];
  __asm {
    movups xmm0, [buf]
    mov [buf], eax
  }

The frontend size in this case (1) is wrong, and the register makes the
instruction matching unambiguous. There are also enough bytes available
that we shouldn't complain to the user that they are potentially using
an incorrectly sized instruction to access the variable.

Supersedes D32636 and D26586 and fixes PR28266

David Majnemer f8b569c786 [ms-inline-asm] Handle dependent identifiers in inline asm 
Build up a dependent expression for MS-style inline assembly if the
identifier's type is dependent.

This fixes PR26001.

Reid Kleckner 14e96b4930 [ms-inline-asm] Add field access to MS inline asm identifier lookup 
Now we can parse code like this:
  struct A {
    int field;
  };
  int f(A o) {
    __asm mov eax, o.field
  }

Fixes PR19117.
