    [to-be-committed][RISC-V][PR target/115142] Do not create invalidate
shift-add insn

    The circumstances which triggered this weren't something that should appear
in
    the wild (-ftree-ter, without optimization enabled).  So I wasn't planning
to
    backport.  Obviously if it shows up in another context we can revisit that
    decision.

    I've run this through my rv32gcv and rv64gc tester.  Waiting on the CI
system before committing.
