    aarch64: Fix ICE happening in SET_TYPE_VECTOR_SUBPARTS with libgccjit

    The structure aarch64_simd_type_info was split in 2 because we do not
    want to reset the static members of aarch64_simd_type_info to their
    default value. We only want the tree types to be GC-ed. This is
    necessary for libgccjit which can run multiple times in the same
    process. If the static values were GC-ed, the second run would
    ICE/segfault because of their invalid value.

    The following test suites passed for this patch:

     * The aarch64 tests.
     * The aarch64 regression tests.

    The number of failures of the jit tests on aarch64 lowered from +100 to
    ~7.
