[libcxx-commits] [libcxx] [libcxx] Add local %T substitution (PR #160026)

[Aiden Grossman via libcxx-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/160026

This patch adds a %T substitution directly into the libc++ test format.
This ensures that the libc++ test format will continue to work when we
remove support for %T in llvm lit.
