Fix handling of X86_TUNE_AVOID_512FMA_CHAINS.
I have noticed quite bad pasto in handling of X86_TUNE_AVOID_512FMA_CHAINS. At the
moment it is ignored, but X86_TUNE_AVOID_256FMA_CHAINS controls 512FMA too.
This patch fixes it, we may want to re-check how that works on AVX512 machines.
gcc/ChangeLog:
* config/i386/i386-options.cc (ix86_option_override_internal): Fix
handling of X86_TUNE_AVOID_512FMA_CHAINS.
