function.c (assign_stack_temp_for_type): Abort if mode == Blkmode and align is less than BIGGEST_ALIGNMENT / BITS_PER_UNIT.

        * function.c (assign_stack_temp_for_type): Abort
        if mode == Blkmode and align is less than
        BIGGEST_ALIGNMENT / BITS_PER_UNIT.
        (assign_stack_temp_for_type): Round the size parameter
        passed to assign_stack_local instead of size itself.
Bootstrapped on the PA and x86.
