    Fix PR 108582: ICE due to PHI-OPT removing a still in use ssa_name.

    This patch adds a check in match_simplify_replacement to make sure the
middlebb
    does not have any phi-nodes as we don't currently move those.
    This was just a thinko from before.

    Ok? Bootstrapped and tested on x86_64-linux-gnu with no regressions?

            PR tree-optimization/108582

    gcc/ChangeLog:

            * tree-ssa-phiopt.cc (match_simplify_replacement): Add check
            for middlebb to have no phi nodes.

    gcc/testsuite/ChangeLog:

            * gcc.dg/pr108582-1.c: New test.=
