In 53bfcdee, we added load/store_scratch instructions which deviate
a little bit from most memory load/store instructions in that we can't
use the normal untyped read/write instructions which can read and write
up to a vec4 at a time.  Instead, we have to use the DWORD scattered
read/write instructions which are scalar.  To handle this, we added code
to brw_nir_lower_mem_access_bit_sizes to cause them to be scalarized.
However, one case was missing: the load-as-larger-vector case.  In this
case, we take small bit-sized constant-offset loads replace it with a
32-bit load and shuffle the result around as needed.

For scratch, this case is much trickier to get right because it often
emits vec2 or wider which we would then have to lower again.  We did
this for other load and store ops because, for lower bit-sizes we have
to scalarize thanks to the byte scattered read/write instructions being
scalar.  However, for scratch we're not losing as much because we can't
vectorize 32-bit loads and stores either.  It's easier to just disallow
it whenever we have to scalarize.

This adds support for building clover/llvmpipe and running the
piglit CL tests on it.

It uses the gl testing container, and add builds the libclc
spirv libraries as part of that which requires the llvm spirv
translator in the build container.

It also builds the llvm spirv translator as part of the build
root and creates a mesa build that builds clover for testing
against it. It uses llvm 10 as the baseline.

This drops bswap as it has an oob memory access with llvmpipe
which cause flaky test results. phatk also seems flaky

This commit enables clover support for iris.  It is intended as a
compiler developer tool and not as a new OpenCL implementation from
Intel.  If you want competent OpenCL, we have a different open-source
driver for that built on our LLVM-based IGC compiler stack.  However,
using clover with iris is becoming increasingly useful as a compiler
development tool and I'm getting tired of carrying the patches in a
private branch.

By default, clover will not initialize on iris.  To enable clover, set
the IRIS_ENABLE_CLOVER environment variable to "1" or "true".  As we've
done with the semi-sketchy platform support in ANV, it dumps a very loud
WARNING to stderr when enabled.  Use at your own risk.

NOTE: To anyone intending to benchmark this, the performance is going to
be terrible and that is expected.  This is in no way representative of
the Intel/NIR compiler stack.  As it currently stands, clover passes
-O0 to clang when compiling OpenCL C to make SPIRV-LLVM-Transator work.
When compiling the SPIR-V, clover currently doesn't run any NIR
optimizations before it lowers memory access so any NIR optimizations
iris attempts to do are severely hampered.  One day, clover will get a
NIR optimization loop or the ability to hand things off to the driver
per-lowering but today is not that day.
