9fa1cdfe7f intel/rt: Implement push constants as global memory reads 
They're not really "push" anymore but that's because there is no such
thing as push constants in bindless shaders on Intel.  They should be
fast enough, though.  There is some room for debate here as to whether
we want to do the pull in NIR or push it into the back-end.  The
advantage of doing it in the back-end is that it'd be easier to use
MOV_INDIRECT for indirect push constant access rather than falling back
to a dataport message.

ca88cd8e5a intel/rt: Add return instructions at the end of ray-tracing shaders 
Each callable ray-tracing shader shader stage has to perform a return
operation at the end.  In the case of raygen shaders, it retires the
bindless thread because the raygen shader is always the root of the call
tree.  In the case of any-hit shaders, the default action is accep the
hit.  For callable, miss, and closest-hit shaders, it does a return
operation.  The assumption is that the calling shader has placed a
BINDLESS_SHADER_RECORD address for the return in the first QWord of the
callee's scratch space.  The return operation simply loads this value
and calls a btd_spawn intrinsic to jump to it.

7280b0911d intel/compiler: Add support for bindless shaders 
The Intel bindless thread dispatch model is very simple.  When a compute
shader is to be used for bindless dispatch, it can request a set of
stack IDs.  These are allocated per-dual-subslice by the hardware and
recycled automatically when the stack ID is returned.  Passed to the
bindless dispatch are a global argument address, a stack ID, and an
address of the BINDLESS_SHADER_RECORD to invoke.  When the bindless
shader is dispatched, it is passed its stack ID as well as the global
and local argument pointers.  The local argument pointer is the address
of the BINDLESS_SHADER_RECORD plus some offset which is specified as
part of the BINDLESS_SHADER_RECORD.

payload via an integer location.  This was quite annoying for the parser
and potentially error-prone.  The final KHR version of the SPIR-V
ray-tracing spec replaces these integers with actual pointers.  We don't
really need to implement the NV versions but we have the code and
someone might want to parse some NV ray-tracing shaders.

In bison's commit 72c9fa4510eb (skeletons: use "end of file" instead of
"$end") in bison-3.6, '$end' was changed to 'end of file' in error
messages. Since our glcpp test cases contain the expected output text,
they rely on the particular messages printed by bison. The test case
084-unbalanced-parentheses fails when Mesa is built with bison-3.6 due
to this change.

To allow the test to pass on all supported versions of bison, we:

   1. Change '$end' -> 'end of file' in the .expected file, and
   2. Normalize the error generated by the test case with the same
      replacement

783b895ec9 nir: Rewrite lower_undef_to_zero 
This both fixes its metadata handling (it was flagging dirty regardless
of progress) and reduces the entire pass to 21 LOC including whitespace
by making better use of helpers.

ff05da7f8d microsoft: Add CLC frontend and kernel/compute support to DXIL converter 
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.
