Hi,
I figured I'd just go ahead and post this patch as well since it seems
to have fixed the arc build problems.
It would be nice if someone could bootstrap/regtest if Jeff hasn't
already done so. I was able to verify that the two testcases attached
to the PR build cleanly but not much more.

This patch addresses a code quality regression in GCC 12 by implementing
some constant folding/simplification transformations for REDUC_PLUS_EXPR
in match.pd. The motivating example is gcc.dg/vect/pr89440.c which with
-O2 -ffast-math (with vectorization now enabled) gets optimized to:
