While here, also don't delete that many shaders when we have to evict. For fs,

however certainly shader recompiles have a high cost too so I don't think
evicting one quarter of the cache size makes sense (and, if we're evicting
based on IR count, we probably typically evict only very few or just one

This was implemented since forever, but not enabled.
It passes all piglit tests except one, arb_pipeline_statistics_query-frag.
The reason is that the test (for drawing a 10x10 rect) expects between
100 and 150 pixel shader invocations. But since llvmpipe counts this with
4x4 granularity (and due to the rect being 2 tris) we end up with 224
invocations. I believe however what llvmpipe is doing violates neither the
spirit nor the letter of the spec (our fragment shader granularity really
is 4x4 pixels, albeit we will bail out early on 2x2 or 4x2 (the latter
if AVX is available) granularity), the spec allows to count additional

For bilinear filtering, we don't care if we end up with an incorrect
texel, as long as the filter weight is 0.0 for it. Likewise, the order of
the texels doesn't actually matter (as long as they still have the correct
filter weight).
But for gather, these tricks lead to incorrect results.

mesa/main: Fix GetTransformFeedbacki64 for glTransformFeedbackBufferBase

The spec has special rules for querying buffer offsets and sizes
when BindBufferBase is used, described  in the OpenGL 4.6 spec,
section 6.8 Buffer Object State:

   "To query the starting offset or size of the range of a buffer
    object binding in an indexed array, call GetInteger64i_v with
    target set to respectively the starting offset or binding size
    name from table 6.5 for that array. Index must be in the range
    zero to the number of bind points supported minus one. If the
    starting offset or size was not specified when the buffer object
    was bound (e.g. if it was bound with BindBufferBase), or if no
    buffer object is bound to the target array at index, zero is
    returned."

Transform feedback buffer queries should follow the same rules, since
it is the same case for them. There is a CTS test for this.

llvmpipe, draw: increase shader cache limits

We're not particularly concerned with memory usage, if the tradeoff is
shader recompiles. And it's common for apps to have a lot of shaders
nowadays (and, since our shaders include a LOT of context state of course
we may create quite a bit more shaders even).
So quadruple the amount of shaders draw will cache (from 128 to 512).
For llvmpipe (fs shaders) quadruple the number of instructions, keep the
number of variants the same for now (only with very simple, non-texturing
shaders the variant limit could really be reached), and simplify the
definition, it's probably easier to just have one different definition
per branch...
