        PR middle-end/92046
        * opts.c (finish_options): Do not influence global --params
        from options that are adjustable per function.
        * tree-vect-data-refs.c (vect_enhance_data_refs_alignment):
        Apply --param adjustment based on active cost-model.
        * tree-ssa-phiopt.c (cond_if_else_store_replacement): Disable
        further store-sinking when vectorization or if-conversion
        are not enabled.
