  [clang] Check constexpr int->enum conversions consistently. (#143034)

In 8de51375f12d91675a18d17f262276e65f43fbe0 and related patches, we
added some code to avoid triggering -Wenum-constexpr-conversion in some
cases. This isn't necessary anymore because -Wenum-constexpr-conversion
doesn't exist anymore. And the checks are subtly wrong: they exclude
cases where we actually do need to check the conversion. This patch gets
rid of the unnecessary checks.
