    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.

            PR tree-optimization/114672
            * tree-ssa-math-opts.cc (convert_plusminus_to_widen): Only
            allow mode-precision results.

            * gcc.dg/torture/pr114672.c: New testcase.

    (cherry picked from commit 912753cc5f18d786e334dd425469fa7f93155661)
