Do not overwrite hidden access flags for intrinsics

Deduplicating warnings works by overwriting the runtime access flags
of a method/field to move it from a greylist to the whitelist. This
triggers a CHECK when attempted on an intrinsic as their ordinal bits
clash with the hidden API access flags. Do not attempt to deduplicate
for those.
