    aarch64: Fix __builtin_apply with -mgeneral-regs-only [PR113486]

    The problem here is the builtin apply mechanism thinks the FP registers
    are to be used due to get_raw_arg_mode not returning VOIDmode. This
    fixes that oversight and the backend now returns VOIDmode for
non-general-regs
    if TARGET_GENERAL_REGS_ONLY is true.

    Built and tested for aarch64-linux-gnu with no regressions.

            PR target/113486

    gcc/ChangeLog:

            * config/aarch64/aarch64.cc (aarch64_get_reg_raw_mode): For
            TARGET_GENERAL_REGS_ONLY, return VOIDmode for non-GP_REGNUM_P
regno.

    gcc/testsuite/ChangeLog:

            * gcc.target/aarch64/builtin_apply-1.c: New test.
