Thank you for the review!

These are covered by tests in `inline-defensive-checks.c:150,156,169,179` (old code had `IgnoreParenCasts`). This function is actually used a lot (even more so since https://reviews.llvm.org/D32291), and seems fairly well-tested, so i felt relatively safe when refactoring it.

I'd love to know :o
