Roland Scheidegger f3b1acff48 gallivm: don't use pavg.b intrinsic on llvm >= 6.0
This intrinsic disppeared with llvm 6.0, using it ends up in segfaults
(due to llvm issuing call to NULL address in the jited shaders).
Add code doing the same thing as the autoupgrade code in llvm so it
can be matched and replaced back with a pavgb.

While here, also improve lp_test_format, so it tests both with and without
cache (as it was, it tested the cache versions only, whereas cache is
actually disabled in llvmpipe, and in any case even with it enabled
vertex and geometry shaders wouldn't use it). (Although at least for
the unorm8 uncached fetch, the code is still quite different to what
llvmpipe is using, since that would use unorm8x16 type, whereas
the test code is using unorm8x4 type, hence disabling some intrinsic
paths.)

Fixes: 6f4083143b ("gallivm: use llvm jit code for decoding s3tc")

  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `Freenode's #dri-devel
<irc://chat.freenode.net#dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
