[TySan] Add initial Type Sanitizer support to Clang) (#76260)
This patch introduces the Clang components of type sanitizer: a
sanitizer for type-based aliasing violations.
It is based on Hal Finkel's https://reviews.llvm.org/D32198.
The Clang changes are mostly formulaic, the one specific change being
that when the TBAA sanitizer is enabled, TBAA is always generated, even
at -O0.
It goes together with the corresponding LLVM changes
(https://github.com/llvm/llvm-project/pull/76259) and compiler-rt
changes (https://github.com/llvm/llvm-project/pull/76261)
