[Mesa-dev] radeonsi/compute: Memory usage fixes

[Tom Stellard]

Hi,

This series contains fixes for applications which allocate large amounts
of memory.

The first two patches fix the values reported for
PIPE_COMPUTE_CAP_MAX_GLOBAL_SIZE, PIPE_COMPUTE_CAP_MAX_MEM_ALLOC_SIZE,
and PIPE_SHADER_CAP_MAX_CONST_BUFFER_SIZE so that applications don't
allocate more memory than is available.

The next five patches eliminate some GPU buffer leaks which should fix
long running applications that launch a lot of kernels.

Please Review.

Thanks,
Tom
