Zero'ing the allocation and calling initialize_ssa_def() for every
ssa def can be expensive. Since we only use a subset of the allocated
variables, initialize it only when needed.

This adds a standalone library which can convert through the pipeline of
OpenCL C -> SPIR -> SPIR-V -> NIR -> DXIL. It can add in the libclc
implementations of various library functions in the NIR phase, and
also massages the NIR to shift it more towards graphics-style compute.
This is leveraged by the out-of-tree OpenCLOn12 runtime
(https://github.com/microsoft/OpenCLOn12).
This is the combination of a lot of commits from our development branch,
containing code by several authors.

Without this patch, copy propagation pass can optimize out
buffer loads out of compare & swap loop, which then leads
to infinite loop.

It is UB to initialize unions on the stack and rely on bits not covered
by the initialized union member to be zero. Lets just simplify it and
move the entire nir_const_value off the stack.
While we're in there, sprinkle around some const.

This cleans up a bunch of gross sprintfs and keeps the caller from needing
to remember to ralloc_strdup. I added a couple of '"%s", name ? name :
""' to radv where I didn't fully trace through whether a non-null name was
being passed in.
I also took the liberty of adding a basic name to a few shaders (pan_blit,
unit tests)

We can use num_blocks (if it's been initialized by some pass indexing
blocks) to pre-size our table, which helps on validating shaders with many
blocks which would otherwise reallocate the set several times.
No statistically significant performance difference on softpipe
KHR-GL33.texture_swizzle.functional runtime (n=15). A previous, similar
variant of this patch cut .3% of instructions in softpipe shader-db ./run
shaders/closed/steam/borderlands-2/35* (an arbitrary set of shaders that
completed in reasonable amount of time) according to callgrind.

We need to consider shader calls as potential writes to their payloads.
For other ray-tracing intrinsics, we may not have a shader payload
pointer and have to treat them more like a barrier. We also need to
ensure that global and SSBO reads/writes aren't propagated across shader
call intrinsics.
