That is fantastic, lots of nice wins!

At the moment, performance is a mixed bag. Some tests are up and some
are down. In particular I believe Speedometer is down a few percent.
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
+1. This is really fantastic news, and frankly happened way faster than I
would have thought possible. Thanks to everyone involved!

How does the performance of clang-cl builds compare to MSVC builds on
benchmarks like Speedometer?
