tree-optimization/114672 - WIDEN_MULT_PLUS_EXPR type mismatch
The following makes sure to restrict WIDEN_MULT*_EXPR to a mode
precision final compute type as the mode is used to find the optab
and type checking chokes when seeing bit-precisions later which
would likely also not properly expanded to RTL.

allow mode-precision results.

Confirmed bug exists in gcc-12 and gcc-13. Backport applies cleanly and fixes
the issue. I'll request a backport on the mailing list
