IIRC, there were already comparisons (about other software) clearly
indicating Clang-built binary performance being superior to created by MSVC.
The only thing I would love to note is that besides performance, there's
also usability of development tools that matters. If changing to Clang
as compiler on Windows would mean we can't use Visual Studio's debugger
(or its use would be less efficient), it would be a really sad thing.
OTOH, I hope that today, Visual Studio works much better with
clang-built binaries (it even suggests clang as part of its components
when installing, which we use for Skia, so we already have it on Windows
