d14d5b4223 Add support for unreachable and undef

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.

30483b0c84 Teach the X86 backend about unreachable and undef. Among other things, we 
now compile:

'foo() {}' into "ret" instead of "mov EAX, 0; ret"

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.

This patch is contributed by Jeff Cohen!

e0c83a86b0 Better codegen of binary integer ops with 32 bit immediate operands. 
This transformation fires a few dozen times across the testsuite.

For example, int test2(int X) { return X ^ 0x0FF00FF0; }
Old:
_test2:
        lis r2, 4080
        ori r2, r2, 4080
        xor r3, r3, r2
        blr

New:
_test2:
        xoris r3, r3, 4080
        xori r3, r3, 4080
        blr

bab2adf496 * Make a PPC32-specific code emitter because we have separate classes for 32- 
and 64-bit code emitters that cannot share code unless we use virtual
  functions
* Identify components being built by tablegen with more detail by assigning them
  to PowerPC, PPC32, or PPC64 more specifically; also avoids seeing 'building
  PowerPC XYZ' messages twice, where one is for PPC32 and one for PPC64
