Full target Windows binaries no longer available

[Mr-Wiseguy]

As pointed out in #110536, the Windows installer llvm releases recently removed all targets other than AArch64, ARM and X86. This wasn't an issue as a separate tar.xz archive (e.g. LLVM-19.1.3-Windows-X64.tar.xz) which included all targets was also present in releases. However, since 19.1.4 that archive has been omitted from the releases. Will builds be available that support other targets for Windows in future versions? These are relied on by projects as they offered a very convenient way to cross compile for non-desktop architectures on Windows without having to maintain a custom toolchain.

I'm not sure I fully understand the details in that linked PR. Does that mean there will no longer be builds that support the full target set for cross compilation? The PR references community builds, but I'm not sure where those would be or if they're configured with all target support.

The removal of full target support from the Windows installs has caused many issues for my projects now that it's propagated around. For example, GitHub runners and the Visual Studio distribution of clang have both lost cross compilation support because they seem to use the provided Windows builds. Myself and others who rely on it would really appreciate it if the decision to remove that functionality was reconsidered.

Building mips code out of the box on Windows with MSVC Build Tools is now no longer possible because of this decision.
