    c-family: Fix ICE on __builtin_speculation_safe_value () [PR94755]

    When this builtin has no parameters, speculation_safe_value_resolve_call
    returns BUILT_IN_NONE, but resolve_overloaded_builtin uselessly
    dereferences the first param just to return error_mark_node immediately.

    The following patch rearranges it so that we only read the first parame=
ter
    if fncode is not BUILT_IN_NONE.
