  Target Milestone: ---

We found on Intel platform, commit r13-128-g938a02a589dc22
(938a02a589dc22cef65bba2b131fc9e4874baddb) results 53.7% codesize increment
when compiled with march_native_ofast_lto(-march=native -Ofast -funroll-loops
-flto) for specrate 538.imagick_r on SkylakeW, Cascade Lake and IceLake.

On Zen3 Server/Client code size looks alright.
