Owen Anderson c004eec71b When adding the carry bit to another value on X86, exploit the fact that the carry-materialization

(sbbl x, x) sets the registers to 0 or ~0.  Combined with two's complement arithmetic, we can fold
the intermediate AND and the ADD into a single SUB.

This fixes <rdar://problem/8449754>.
