softpipe: Split 3D to 2D coords conversion into separate function

This is to avoid tying the conversion to the sampling -
textureQueryLod will need to do the conversion too, but it does not do
any sampling.

So instead of a "get_samples" vfunc, there is just a bool saying
whether the conversion is needed or not. This solution keeps a nice
property of not adding any overhead for the common case (2D textures).

v2:
  - replaced the "convert_coords" vfunc with a "need_cube_convert"
    boolean to avoid overhead of copying arrays in common case
  - removed an unused typedef

v2:

i965: Advertise 65536 for GL_MAX_UNIFORM_BLOCK_SIZE.

Our old value of 16384 is the minimum value.  DirectX apparently
requires 65536 at a minimum; that's also what nVidia and the Intel
Windows driver advertise.  AMD advertises MAX_INT.

Ilia Mirkin noticed that "Shadow Warrior" uses UBOs larger than 16k
on Nouveau, which advertises 65536 bytes for this limit.  Traces
captured on Nouveau don't work on i965 because our lower limit causes
the GLSL linker to reject the captured shaders.  While this isn't
important in and of itself, it does suggest that raising the limit
would be beneficial.

We can read linear buffers up to 2^27 bytes in size, so raising this
should be safe; we could probably even go larger.  For now, matching
nVidia and Intel/Windows seems like a good plan.

We have to reinitialize MaxCombinedUniformComponents as core Mesa will
have set it based on a stale value for MaxUniformBlockSize.

According to Tapani, there's an unreleased game that asserts on this.

nv50/ir: make edge splitting fix up phi node sources

Unfortunately nv50_ir phi nodes aren't directly connected to the CFG, so
the mapping between source and the actual BB is by inbound edge order.
So when manipulating edges one has to be extremely careful. We were
insufficiently careful when splitting critical edges which resulted in
the phi nodes being confused as to where their sources were coming from.

This primarily manifests itself with the TXL-lowering logic on nv50,
when it is inside of a conditional. I've been unable to trigger the
issue anywhere else so far. This resolves rendering failures
in a number of games like Two Worlds 2, Trine: Enchanted Edition, Trine 2,
XCOM:Enemy Unknown, Stacking. It also improves the situation in
Hearthstone, Sonic Generations, and The Raven: Legacy of a Master Thief.
However more work needs to be done there (splitting a lot more edges
solves it, so it's some other sort of RA-related issue).

nvc0: keep track of cb bindings per buffer, use for upload settings

CB updates to bound buffers need to go through the CB_DATA endpoints,
otherwise the shader may not notice that the updates happened.
Furthermore, these updates have to go in to the same address as the
bound buffer, otherwise, again, the shader may not notice updates.

So we keep track of all the places where a constbuf is bound, and
iterate over all of them when updating data. If a binding is found that
encompasses the region to be updated, then we use the settings of that
binding for the upload. Otherwise we upload as a regular data update.

This fixes piglit 'arb_uniform_buffer_object-rendering offset' as well
as blurriness in Witcher2.
