79a564caa7 Fix a type violation

2d4c98d79b Finally fix one of the oldest FIXMEs in the PowerPC backend: correctly
flag rotate left word immediate then mask insert (rlwimi) as a two-address
instruction, and update the ISel usage of the instruction accordingly.

This will allow us to properly schedule rlwimi, and use it to efficiently
codegen bitfield operations.

involving %B instead of allowing any geps except %A's.

358a9027a8 Instruction select globals with offsets better. For example, on this test
case:

int C[100];
int foo() {
  return C[4];
}

We now codegen:

foo:
        mov %EAX, DWORD PTR [C + 16]
        ret

instead of:

foo:
        mov %EAX, OFFSET C
        mov %EAX, DWORD PTR [%EAX + 16]
        ret

Other impressive features may be coming later.
