Okay,so i tried this on large bc files (all of clang, etc) i have around.

The amount of time spent in remangling is almost not measureable.
For clang, it claims 100 microseconds.
I'm not sure it has that kind of measurement accuracy, but i can't find a large testcase where i can measure any real amount of time spent here.

So i'm going to commit this, but we should definitely revert and try to focus it more if we do find a testcase that matters.

(the worrying code i can think of would be millions of lines of avx512 or neon intrinsics or something)
