Add/Sub/Mul are safe to promote here as well. Incrementing a single-bit

bitfield now gives this code:
_plus:

rlwimi r2, r2, 0, 1, 31
xoris r2, r2, 32768
stw r2, 0(r3)
blr
instead of this:
_plus:
lwz r2, 0(r3)
srwi r4, r2, 31
slwi r4, r4, 31
addis r4, r4, -32768
rlwimi r2, r4, 0, 0, 0
stw r2, 0(r3)

this can obviously still be improved.

Implement simple promotion for cast elimination in instcombine. This is
...
currently very limited, but can be extended in the future. For example,
we now compile:
uint %test30(uint %c1) {
%c2 = cast uint %c1 to ubyte
%c3 = xor ubyte %c2, 1
%c4 = cast ubyte %c3 to uint
ret uint %c4
}
to:
_xor:
movzbl 4(%esp), %eax
xorl $1, %eax
ret
instead of:
_xor:
movb $1, %al
xorb 4(%esp), %al
movzbl %al, %eax
ret
More impressively, we now compile:
struct B { unsigned bit : 1; };
void xor(struct B *b) { b->bit = b->bit ^ 1; }
To (X86/PPC):
_xor:
movl 4(%esp), %eax
xorl $-2147483648, (%eax)
ret
_xor:
lwz r2, 0(r3)
xoris r2, r2, 32768
stw r2, 0(r3)
blr
instead of (X86/PPC):
_xor:
movl 4(%esp), %eax
movl (%eax), %ecx
movl %ecx, %edx
shrl $31, %edx
# TRUNCATE movb %dl, %dl
xorb $1, %dl
movzbl %dl, %edx
andl $2147483647, %ecx
shll $31, %edx
orl %ecx, %edx
movl %edx, (%eax)
ret
_xor:
lwz r2, 0(r3)
srwi r4, r2, 31
xori r4, r4, 1
rlwimi r2, r4, 31, 0, 0
stw r2, 0(r3)
blr
This implements InstCombine/cast.ll:test30.
