    c: Handle REALPART_EXPR and IMAGPART_EXPR in fold_offsetof [PR105555]

    In some cases the C front-end calls into fold_offsetof to fold
    an address but that does not handle REALPART_EXPR nor IMAGPART_EXPR so
    gcc produces an internal compiler error. For offsetof,
REALPART_EXPR/IMAGPART_EXPR
    won't show up which is why they were not there before.

    Bootstrapped and tested on x86_64-linux-gnu.
