Adam Paszke 265a54da31 [Mosaic GPU] Pass in TMA descriptors through kernel parameters
As we've established (sigh) we can't pass in TMA descriptors through global memory.
The current workaround was to use constant memory instead, but this raises a number of
potential concurrency issues. So, instead, we use the freshly added support for grid_constant
parameters in upstream LLVM to pass the descriptors as kernel arguments. This seems to work
fine and should in fact have lower overheads than both previous methods.
