Would relaxing that in TER for constants help in the case of:
static inline __attribute__((always_inline)) ...
foo (..., int m = __ATOMIC_SEQ_CST)
__atomic_test_and_set (&x, m);
foo (..., __ATOMIC_HLE_ACQUIRE | __ATOMIC_SEQ_CST);
though? I'd think as the temp = 0x10005; would be in a different bb, TER
wouldn't do anything here, for -O1 of course CCP or similar would propagate
that, but for -O0 we'd still have to walk the chain of SSA_NAMEs.
