[PATCH 3/4] libsanitizer: Improve FrameIsInternal

[Kito Cheng]

`FrameIsInternal` is a function that improves report quality by filtering out
internal functions from the sanitizer, allowing it to point to a more precise
root cause. However, the current checks are mostly specific to compiler-rt,
so we are adding a few more rules to enhance the filtering for libsanitizer as
well.
