Florian Hahn c135f6ffe2 [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)
