For example, on:

#include <emmintrin.h>
int foo(int N) {
 __m128i white2;
 white2 = _mm_slli_si128(white2, N);
 return 0;
} 

we used to get:
fatal error: error in backend: Cannot yet select: intrinsic %llvm.x86.sse2.psll.dq

now we get:
/Users/sabre/t.c:4:11: error: argument to '__builtin_ia32_pslldqi128' must be a
      constant integer
 white2 = _mm_slli_si128(white2, N);

Better diagnostic for superfluous scope specifier inside a class definition for member functions. + Fixit.

Example: 
class A {
   void A::foo(); //warning: extra qualification on member 'foo'

(With a few minor bug fixes from me).

one results in an obscure error from the backend that doesn't make
sense.  Capture this information in the .def files for builtins with
a new "I" modifier letter indicating the an argument needs to be an ICE.

Nothing uses this yet, but sema will eventually enforce this (eliminating
some special cases from semachecking.cpp) and codegen will use this to 
force an ICE value, preventing backend error messages.
