Unless it changed *very* recently, LLVM tools are built by the default
target (`all') on Windows (both VS and Mingw). Tests should work out of
the box too. Examples are not built by default, but you can either add
them to the `all' target (with -DLLVM_BUILD_EXAMPLES=ON) or explictly
build them using its associated targets.
By default, only X86 (not ARM) is built on Windows, but you can change
that. See LLVM_TARGETS_TO_BUILD in
Since yesterday, you twisted your memory quite a bit :-)

Yes, Python is required by the LLVM CMake build. Possibly by the
configure&make build too (I'm not sure, but the plan was for that build
to depend on Python too.) CMake doesn't *need* Python at all, the LLVM
CMake build worked without Python for years.
