The way we handle spilling for fp64 in vec4 is to emit a series of MOVs
which swizzles the data around and then a pair of 32-bit spills. This
works great except that the next time we go to pick a spill reg, the
compiler isn't smart enough to figure out that the register has already
been spilled. Normally we do this by looking at the sources of spill
instructions (or destinations of fills) but, because it's separated from
the actual value by a MOV, we can't see it. This commit adds a new
opcode VEC4_OPCODE_MOV_FOR_SCRATCH which is identical to MOV in
semantics except that it lets RA know not to spill again.

The vec4 back-end can't push UBOs just yet but it soon will be able.
When it starts pushing UBOs, it will have a lower limit than scalar due
to a crummy register allocator. Mirror that limit in ANV so we don't
run into asserts due to ANV and the back-end making different choices.

This change adds a gallium D3D10 state tracker that works as a WDDM UMD
software driver, similar to Microsoft WARP, but using llvmpipe/softpipe.
The final deliverable is a d3d10sw.dll, which is similar to WARP's
d3d10warp.dll.
This has been used to run Microsoft Windows HCK wgf11* tests with
llvmpipe, and they were at one point passing 100%.
Known limitations:
- TGSI (no NIR)
- D3D10 only (no D3D11 support yet)
- no WINE integration (WINE doesn't implement WDDM DDI.)
For further details see:

Another lavapipe leak found with LeakSanitizer.
This happens when using tessellation without geometry shader but with a
fragment shader that consumes primitive ID, therefore requiring
primitive assembler stage.

This prevents read buffer overflows in dup_vertex(), when draw stages
allocate extra shader outputs after the vertex buffers are allocated.
The original issue can be exercised with upcoming
piglit/tests/general/vertex-fallbacks.c test.
