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.
