TGSI_OPCODE_KIL and KILP had confusing names. The former was conditional
kill (if any src component < 0). The later was unconditional kill.
At one time KILP was supposed to work with NV-style condition
codes/predicates but we never had that in TGSI.
This patch renames both opcodes:
TGSI_OPCODE_KIL -> KILL_IF (kill if src.xyzw < 0)
TGSI_OPCODE_KILP -> KILL (unconditional kill)
Note: I didn't just transpose the opcode names to help ensure that I
didn't miss updating any code anywhere.
I believe I've updated all the relevant code and comments but I'm
not 100% sure that some drivers had this right in the first place.
For example, the radeon driver might have llvm.AMDGPU.kill and
llvm.AMDGPU.kilp mixed up. Driver authors should review their code.

For conditional rendering this makes it possible to skip rendering
if either the predicate is true or false, as supported by d3d10
(in fact previously it was sort of implied skip rendering if predicate
is false for occlusion predicate, and true for so_overflow predicate).
There's no cap bit for this as presumably all drivers could do it trivially
(but this patch does not implement it for the drivers using true
hw predicates, nvxx, r600, radeonsi, no change is expected for OpenGL
functionality).

This is the only sane solution for nv50 and nvc0 (really, trust me),
but since on other hardware the border colour is tightly coupled with
texture state they'd have to undo the swizzle, so I've added a cap.
The dependency of update_sampler on the texture updates was
introduced to avoid doing the apply_depthmode to the swizzle twice.
v2: Moved swizzling helper to u_format.c, extended the CAP to
provide more accurate information.

TGSI_OPCODE_IF condition had two possible interpretations:
- src.x != 0.0f
- Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was false either for
vertex and fragment shaders
- gallivm/llvmpipe
- postprocess
- vl state tracker
- vega state tracker
- most old drivers
- old internal state trackers
- many graw examples
- src.x != 0U
- Mesa statetracker when PIPE_SHADER_CAP_INTEGERS was true for both
vertex and fragment shaders
- tgsi_exec/softpipe
- r600
- radeonsi
- nv50
And drivers that use draw module also were a mess (because Mesa would
emit float IFs, but draw module supports native integers so it would
interpret IF arg as integers...)
This sort of works if the source argument is limited to float +0.0f or
+1.0f, integer 0, but would fail if source is float -0.0f, or integer in
the float NaN range. It could also fail if source is integer 1, and
hardware flushes denormalized numbers to zero.
But with this change there are now two opcodes, IF and UIF, with clear
meaning.
Drivers that do not support native integers do not need to worry about
UIF. However, for backwards compatibility with old state trackers and
examples, it is advisable that native integer capable drivers also
support the float IF opcode.
I tried to implement this for r600 and radeonsi based on the surrounding
code. I couldn't do this for nouveau, so I just shunted IF/UIF
together, which matches the current behavior.

The glsl-to-tgsi translater will emit SQRT to implement GLSL's sqrt()
and distance() functions if the PIPE_SHADER_CAP_TGSI_SQRT_SUPPORTED
query says it's supported by the driver.
Otherwise, sqrt(x) is implemented with x*rsq(x). The problem with
this is sqrt(0) must be handled specially because rsq(0) might be
Inf/NaN/undefined (and then 0*rsq(0) is Inf/Nan/undefined). In the
glsl-to-tgsi code we use an extra CMP to check if x is zero and then
replace the result of x*rsq(x) with zero.
In the end, this makes sqrt() generate much more reasonable code for
drivers that can do square roots.
Note that many of piglit's generated shader tests use the GLSL
distance() function.

This allows updating only a subrange of buffer bindings.
set_vertex_buffers(pipe, start_slot, count, NULL) unbinds buffers in that
range. Binding NULL resources unbinds buffers too (both buffer and user_buffer
must be NULL).
The meta ops are adapted to only save, change, and restore the single slot
they use. The cso_context can save and restore only one vertex buffer slot.
The clients can query which one it is using cso_get_aux_vertex_buffer_slot.
It's currently set to 0. (the Draw module breaks if it's set to non-zero)
It should decrease the CPU overhead when using a lot of meta ops, but
the drivers must be able to treat each vertex buffer slot as a separate
state (only r600g does so at the moment).
I can imagine this also being useful for optimizing some OpenGL use cases.

We're starting to get apps utilizing more than 16 varyings and
most current hardware supports 32 anyway.
Tested with r600g.
swrast, softpipe and llvmpipe still advertise 16 varyings.
This fixes a WebGL crash after launching this demo:

NOTE: This is a candidate for the stable branches.

"get_transfer + transfer_map" becomes "transfer_map".
"transfer_unmap + transfer_destroy" becomes "transfer_unmap".
transfer_map must create and return the transfer object and transfer_unmap
must destroy it.
transfer_map is successful if the returned buffer pointer is not NULL.
If transfer_map fails, the pointer to the transfer object remains unchanged
(i.e. doesn't have to be NULL).
