patch for build_conditional_expr

This patch for build_conditional_expr is modeled after build_binary_op in that
it skips the diagnostic if the objc_compare_types verifies that the types are
compatible.

If the maintainers wish, I can follow up with a little optimization for the C
front end for both build_conditional_expr and build_binary_op in that
objc_compare_types will only be called for c_dialect_objc.
