tree-optimization/121595 - new fabs(a+0.0) -> fabs(a) pattern
With -fno-trapping-math it is safe to optimize fabs(a + 0.0) as
fabs (a).
PR tree-optimization/121595
* match.pd (fabs(a + 0.0) -> fabs (a)): Optimization pattern limited to
the -fno-trapping-math case.
* gcc.dg/fabs-plus-zero-1.c: New testcase.
* gcc.dg/fabs-plus-zero-2.c: Likewise.
