Maybe add a test for clc as well? Because:

This patch adds support for x86's single-byte encoded stc (set carry flag)
and clc (clear carry flag) instructions to i386.md.
The motivating example is the simple code snippet:
unsigned int foo (unsigned int a, unsigned int b, unsigned int *c)
{
return __builtin_ia32_addcarryx_u32 (1, a, b, c
