PR tree-optimization/34036
* opts.c (set_fast_math_flags): Do not set flags in common
with set_unsafe_math_optimizations_flags, invoke it directly.
(set_unsafe_math_optimizations_flags): Unset flag_trapping_math
and flag_signed_zeros.
* toplev.c (process_options): Force flag_associative_math to 0 and
warn, if it is set and either flag_trapping_math or flag_signed_zeros
is set too.
* doc/invoke.texi (Optimize Options): Document the new behavior
of -funsafe-math-optimizations, that -fassociative-math requires
both -fno-signed-zeros and -fno-trapping-math and make it clear
that -fno-trapping-math requires -fno-signaling-nans.
