This patch looks reasonable to me, in fact I have the same patch in
my local tree. (Note, I can't approve it).
However, be careful with -fmove-loop-invariants. This pass is really
broken in various ways. I've tried to fix all issues I encountered
in the past two weeks, and I have posted the patches for that. But
there is still at least one bug involving exceptions that we need to
understand better and find a suitable fix for, see PR24762.
