This creates a new toolchain artifact that repacks a combination of the linux64-clang compiler along with parts of the win64-clang-cl compiler. This has multiple advantages: - It removes some convoluted parts of build task definitions (limiting that to only occur on the win-cross toolchain itself). - It simplifies the build setup by not requiring to prepare for where clang-cl.exe is. - It speeds up getting compiler artifacts because the win64-clang-cl artifact is very large (due to there not being a llvm shared library) and bzipped, which is slow to decompress. Here, we only take what we need for the cross builds. - It adds the runtime files that e.g. PGO will require, and that linux clang-cl insists lives in the clang directory, not the win64-clang-cl one, and that would require some convoluted setup to make it work with the two separate toolchains.
