[llvm-branch-commits] [NFC][AST] Clean up XRayFilter and NoSanitizeL before backend (PR #162119)

Changes

I don't thin we need them after AST is destroyed.
If I am wrong we should see crashes immediately, as pointers dereferenced 
unchecked.

Subject: [PATCH] [llvm][mustache] Use single pass when tokenizing

The old implementation used many string searches over the same portions
of the strings. This version sacrifices some API niceness for perf wins.
