    Fix ICE with cast of division by zero (PR c/93348).

    Bug 93348 reports an ICE on certain cases of casts of expressions that
    may appear only in unevaluated parts of integer constant expressions,
    arising from the generation of nested C_MAYBE_CONST_EXPRs.  This patch
    fixes it by adding a call to remove_c_maybe_const_expr in the
    integer-operands case, as is done in other similar cases.

    Bootstrapped with no regressions for x86_64-pc-linux-gnu.

        PR c/93348
    gcc/c:
        * c-typeck.c (build_c_cast): Call remove_c_maybe_const_expr on
        argument with integer operands.

    gcc/testsuite:
        * gcc.c-torture/compile/pr93348-1.c: New test.
