tree-optimization/107647 - avoid FMA from SLP with -ffp-contract=off
Only with -ffp-contract=fast we can synthesize FMA operations like
vfmaddsub231ps, so properly guard the transform in SLP pattern
detection.
PR tree-optimization/107647
* tree-vect-slp-patterns.cc (addsub_pattern::recognize): Only
allow FMA generation with -ffp-contract=fast for FP types.
(complex_mul_pattern::matches): Likewise.
* gcc.target/i386/pr107647.c: New testcase.
