    libsanitizer: Improve FrameIsInternal
    
    `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.
