    c++: -fmerge-all-constants vs. destructors [PR91529]

    cp_finish_decl avoids setting TREE_READONLY on TREE_STATIC variables that
    have non-constant construction or destruction, but -fmerge-all-constants
was
    converting an automatic variable to static while leaving TREE_READONLY set.

    Fixed by clearing the flag in cp_finish_decl in the presence of
    -fmerge-all-constants.
