LLVM MC does not seem to accept multi-line conditionals. This may be
fixable in the future with macros. The Aqua Vanjaram shader spec states
that while buffer_invl2 has been replaced by buffer_inv, the former may
still be used for compatibility. However, this does not seem to be
implemented. For now, fix conditional.

Aqua Vanjaram is intended to have fine-grained coherency
from anywhere to anywhere else using read-acquire and
write-release primitives.
Add a test that writes to memory covered by five
different cache lines, then write-releases, while
another thread read-acquires, then reads those
five locations in memory.
There are nine variations of the test to cover
CPU-GPU, same-GPU and across-GPU, vector instructions and
scalar instructions, and data local to the
acquirer or receiver.

For GC 9.4.0, modifications were made to various shaders since certain
flat_ instructions no longer support glc/slc modifiers (replaced with
nt/sc1/sc0). Instead of repeating conditionals inside various shader
bodies, we can make use of LLVM AMDGCN macros.
This patch modularizes the shader macros into seperated defines. Prior
to the core raw-string literal, each shader now starts with the
SHADER_START literal (".text\n") plus any number of SHADER_MACRO_*
literals. This allows us to seperate the macro definitions logically and
use the pre-processor to only include the required macro groups on a
per-shader basis.

Previously, KFDEvictTest.QueueTest and KFDSVMEvictTest.QueueTest
would create a variable number of wavefronts, one for each 64MB
of memory under test. This ran into limits on the buffers used
by the wavefronts, and may at some point have exceeded the
wavefront limit.
Restrict the number of wavefronts to 512, and adjust the shader
to accomodate a variable buffer size

A gfx940 code path was erroneously added to this shader.
It's unneccesary; without this path, the shader uses
the scalar store, which works just fine on gfx940 without changes.
Remove it.

gfx940 changed the semantics of the glc and slc coherency options
on vector stores and loads. This means that shaders that use
those bits no longer compile on gfx940.
Add precompilation if statements to those shaders to use the
new coherency bits.
Also add gfx940 to ASMTest so that compilation is tested.
Note: One of the tests enabled by this patch on gfx940,
KFDEvictTest.QueueTest, does not pass on gfx940 emulators.

This patch restructures the CWSR basic test and allows for
creating parameterized CWSR tests. This patch introduces four
parameterizations. These tests behave as follows:
This test dispatches the IterateIsa shader, which continuously
increments a vgpr for (num_witems / WAVE_SIZE) waves. While this shader
is running, dequeue/requeue requests are sent in a loop to trigger
CWSRs.
This test defines a CWSR threshold. Once the number of CWSRs triggered
reaches the threshold, a known-value is filled into the inputBuf to
signal the shader to exit.
4 parameterized tests are defined:
KFDCWSRTest.BasicTest/0
KFDCWSRTest.BasicTest/1
KFDCWSRTest.BasicTest/2
KFDCWSRTest.BasicTest/3
0: 1 work-item, CWSR threshold of 10
1: 256 work-items, CWSR threshold of 50
2: 512 work-items, CWSR threshold of 100
3: 1024 work-items, CWSR threshold of 1000
Tuple Format: (num_witems, cwsr_thresh)
num_witems: Defines the number of work-items.
cwsr_thresh: Defines the number of CWSRs to trigger.

LoopIsa is a shader that performs a variety of intensive
calculations in a loop. It is used by tests such as
KFDQMTest.QueuePriorityOn*
It contained a scalar load, despite not having any buffer to
read from. This load causes page faults on GFX11. It is
unclear why it did not cause page faults on earlier ASICs.
Remove the load.

Makes use of macros to simplify shader code with instruction-level
differences depending on GFX version. These macros are extensible and
are prepended to every shader so that they are usable everywhere.
