Revert "vulkan/wsi/x11: Ensure we create at least minImageCount images."

This breaks some games like Wolfenstein Youngblood or Wolfenstein 2
that crash at launch if the number of images is more than what they
expected.

We could add vk_x11_strict_image_count to fix these game bugs but
it seems more conservative to revert that change and add a new wsi

mesa/swrast: use logf2 instead of util_fast_log2

The fast version is apparently not accurate enough. I wrote a very

nir: Propagate *2*16 conversions into vectors

If we have code like:

   ('f2f16', ('vec2', ('f2f32', 'a@16'), '#b@32'))

We would like to eliminate the conversions, but the existing rules can't
see into the the (heterogenous) vector. So instead of trying to
eliminate in one pass, we add opts to propagate the f2f16 into the
vector. Even if nothing further happens, this is often a win since then
the created vector is smaller (half2 instead of float2). Hence the above
gets transformed to

   ('vec2', ('f2f16', ('f2f32', 'a@16')), ('f2f16', '#b@32'))

Then the existing f2f16(f2f32) rule will kick in for the first component
and constant folding will for the second and we'll be left with

   ('vec2', 'a@16', '#b@16')

...eliminating all conversions.

v2: Predicate on !options->vectorize_vec2_16bit. As discussed, this
optimization helps greatly on true vector architectures (like Midgard)
but wreaks havoc on more modern SIMD-within-a-register architectures
(like Bifrost and modern AMD). So let's predicate on that.

v3: Extend for integers as well and add a comment explaining the
transforms.
