Detect under-reporting of available memory by initially attempting to
allocate substantially more than reported available memory, and ensure
that the allocation fails. Continue shrinking the attempted allocation
until it succeeds, then fail the test if the successful allocation is
either too much more than or too much less than reported available.

KFDCWSRTest.BasicTest is parameterized to allow an easy method of
tweaking the number of work-items (and save/restores). The input/output
buffers were previously hardcoded to a single page, which would cause a
segmentation fault if the number of work-items specified is greater than
1024 for wave32.

[ROCm/ROCR-Runtime commit: 82a41c7e4d]
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.

KFDExceptionTest.SdmaQueueException allocates VRAM with host access. This
fails on small-BAR GPUs. This error was incorrectly ignored before
7ccda4ba26 ("kfdtest: Full TearDown and SetUp in child process").
The test doesn't really need host access to the memory. Therefore the fix
is to disable the HostAccess flag.

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.

These tests force HW exceptions in the GPU driver. Some of these
exceptions might print page fault error messages at kernel level.
These are expected errors due to the nature of the tests, but still
might cause confusion to users.
