[libcxx] Add local %T substitution

boomanaiden154 · web-flow · commit 37e7ad184d00 · 2025-09-26T15:48:02.000-07:00
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. Reviewers: #reviewers-libcxx, ldionne, philnik777 Pull Request: llvm#160026
