We can't exactly drop the `no_sanitize` entirely as the `containsType()` check
without a category specified will not match against types with the category
`no_sanitize`. So if we removed the check from `isTypeIgnoredBySanitizer()` we
would also have to remove `=no_sanitize` feature all together and just
implicitly have this information from the lack of a category.
In short, let's keep the `no_sanitize` check and perhaps I could add some sort
of caching system for these type checks? Keep in mind these only run when
sanitizers are enabled and after a bunch of other checks too. The runtime hit
should be minimal
