@yus3710-fj  after this patch we get a 7-10% slowdown for 503.bwaves_r from 
SPEC2017. I built with `-Ofast -mcpu=native -fuse-ld=lld -flto`

As I understood it, the previous patch was supposed to enable your 
transformation by default, and this one was only supposed to clean up old 
flags. Did I understand wrong?

Anyway please could you revert this patch and/or fix the regression.
