    sra: Punt for too large _BitInt accesses [PR113330]

    This is the case I was talking about in
    https://gcc.gnu.org/pipermail/gcc-patches/2024-January/642423.html
    and Zdenek kindly found a testcase for it.
    We can only create BITINT_TYPE with precision at most 65535, not 65536,
    so need to punt if we'd want to create it.
