    * gimple-fold.c (gimple_fold_call): Fix a typo in message.  For
    __builtin_unreachable replace the OBJ_TYPE_REF call with a call to
    __builtin_unreachable and add if needed a setter of the lhs SSA_NAME.
    Don't devirtualize for inplace at all.  For targets.length () == 1,
    if the call is noreturn and cfun isn't in SSA form yet, clear lhs.

    * g++.dg/opt/pr59622-2.C: New test.
    * g++.dg/opt/pr59622-3.C: New test.
    * g++.dg/opt/pr59622-4.C: New test.
