    aarch64: Fix PCH for sve builtins [PR123457]

    The problem here is function_table was not in the GGC memory space and not
    streamed out. So even though the builtins were reloaded, function_table was
    a nullptr as it was not reloaded.

    Also noticed initial_indexes should be marked with GTY so it is reloaded
correctly
    from PCH.

    Built and tested for aarch64-linux-gnu.

    gcc/ChangeLog:

            * config/aarch64/aarch64-sve-builtins.cc (struct
registered_function_hasher):
            Change base class to ggc_ptr_hash.
            (initial_indexes): Mark with GTY.
            (function_table): Likewise.
            (handle_arm_sve_h): Allocate function_table from ggc instead of
heap.
