tree-ssa-math-opts: correct -ffp-contract= check
Since tree-ssa-math-opts may freely contract across statement boundaries
we should enable it only for -ffp-contract=fast instead of disabling it
for -ffp-contract=off.
No functional change, since -ffp-contract=on is not exposed yet.
gcc/ChangeLog:
* tree-ssa-math-opts.cc (convert_mult_to_fma): Enable only for
FP_CONTRACT_FAST (no functional change).
