[clang][rtsan] Reland realtime sanitizer codegen and driver (#102622)
This reverts commit a1e9b7e646b76bf844e8a9a101ebd27de11992ff
This relands commit d010ec6af8162a8ae4e42d2cac5282f83db0ce07
No modifications from the original patch. It was determined that the
ubsan build failure was happening even after the revert, some examples:
