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!

ca4f6ebefc Allow machine operands to represent global variables with offsets. This is
useful when you have a reference like:

int A[100];

void foo() { A[10] = 1; }

In this case, &A[10] is a single constant and should be treated as such.

Only MO_GlobalAddress and MO_ExternalSymbol are allowed to use this field, no
other operand type is.

This is another fine patch contributed by Jeff Cohen!!

47eb6567e2 This patch fixes the nasty bug that caused 175.vpr to fail for X86 last night.
The problem occurred when trying to reload this instruction:

MOV32mr %reg2326, 8, %reg2297, 4, %reg2295

The value of reg2326 was available in EBX, so it was reused from there, instead
of reloading it into EDX.

The value of reg2297 was available in EDX, so it was reused from there, instead
of reloading it into EDI.

The value of reg2295 was not available, so we tried reloading it into EBX, its
assigned register.  However, we checked and saw that we already reloaded
something into EBX, so we chose what reg2326 was assigned to (EDX) and reloaded
into that register instead.

Unfortunately EDX had already been used by reg2297, so reloading into EDX
clobbered the value used by the reg2326 operand, breaking the program.

The fix for this is to check that the newly picked register is ok.  In this
case we now find that EDX is already used and try using EDI, which succeeds.

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

promoting the phi to a select is silly because we will always have to do the
