    middle-end/110055 - avoid CLOBBERing static variables

    The gimplifier can elide initialized constant automatic variables
    to static storage in which case TARGET_EXPR gimplification needs
    to avoid emitting a CLOBBER for them since their lifetime is no
    longer limited.  Failing to do so causes spurious dangling-pointer
    diagnostics on the added testcase for some targets.

            PR middle-end/110055
            * gimplify.cc (gimplify_target_expr): Do not emit
            CLOBBERs for variables which have static storage duration
            after gimplifying their initializers.

            * g++.dg/warn/Wdangling-pointer-pr110055.C: New testcase.

    (cherry picked from commit 84eec2916fa68cd2e2b3a2cf764f2ba595cce843)
