[PATCH] D32199: [TySan] A Type Sanitizer (Clang)

[Fangrui Song via Phabricator via cfe-commits]

MaskRay added a comment.

Having the feature will be useful.

`curl -L 'https://reviews.llvm.org/D32199?download=1' | patch -p1` doesn't apply cleanly. This needs a rebase.

+// RUN: %clangxx -no-canonical-prefixes %s -### -o %t.o 2>&1 \
+// RUN:     -target x86_64-unknown-linux -fuse-ld=ld -stdlib=platform -lstdc++ \
----------------
Most `-no-canonical-prefixes` were cargo cult. I have removed them. The test needs a rebase.

Avoid legacy `-target `

`{{.*}}libclang_rt.tysan{{[^.]*}}.a"`

LLVM_ENABLE_PER_TARGET_RUNTIME_DIR=on builds use `libclang_rt.tysan-x86_64.a` (see D107799)
