Please mention in the commit message that the SCons build already
requires 3.9 or later.
Can you add a note about the LLVM requirement and GS support in
docs/relnotes/17.1.0.html, with a separate commit on top ?

With this we have some ~20 preprocessor conditionals which want to be
cleaned up. Look for
$ git grep  "LLVM_.*VERSION\|HAVE_LLVM" -- src/gallium/drivers/swr/
