A quick update about performance: ThinLTO and PGO were enabled for our
clang-cl builds over the last few weeks. These optimizations have
cancelled the previous regressions and brought clang well ahead of

Please keep an eye out for regressions and file a blocking bug for
anything that might be fallout from this change. I'm especially
interested in hearing about the quality

At the moment, performance is a mixed bag. Some tests are up and some

Note however that clang-cl is punching above its weight. These builds
currently have neither LTO nor PGO, while our MSVC builds use both of
those. Any regressi
