[PATCH] D130058: [Clang] Diagnose ill-formed constant expression when setting a non fixed enum to a value outside the range of the enumeration values

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik updated this revision to Diff 448390.
shafik added a comment.

- dyn_cast was not seeing through type sugar switch to `isEnumeralType()`
- `APInt` requires the bit widths to be the same when comparing and so switched to obtaining the value from `Result` from just `getInt()` to `getInt().getSExtValue()` and `getInt().getZExtValue()` which uses the `int64_t` and `uint64_t` overloads.
- Updated some more tests that were failing after fixing the other issues.
