[PATCH] D92440: [dfsan] Support passing non-i16 shadow values in TLS mode

[stephan.yichao.zhao via Phabricator via llvm-commits]

stephan.yichao.zhao updated this revision to Diff 309387.
stephan.yichao.zhao added a comment.

switched to 2-byte alignment to be consistent with 16bit shadow values.

With this alignment, its binary code about TLS is the same as the code before this diff.
For large binaries with original size > 2G, the additional overhead is -0.1%. So its
overall code size overhead is slightly smaller than the current codegen.
