[Hexagon] Generalize builtin for Nd memory alloc with storage scope a…
…nd add lowering for VTCM / Hexagon (apache#10558) * repurpose texture flatten for vtcm; TIR lowering correct * clean up remaining code in texture flatten pass * add Alloc and FreeTexture, but failing to run over rpc * test passing with malloc in the device api * cleanup * fails in very reliable way with memory corruption * working with non-HexagonBuffer vtcm alloc * cleanup * do not pass scope through mem_copy api * [Hexagon] Resolve breakage in test_hexagon/test_cache_read_write Breakage was caused by apache#9727, which didn't account for the new `builtin::mem_copy()` when computing the stack size in `StackSizeChecker`. * use HexagonBuffer in Alloc and Free packed funcs * Added comment indicating need for StackSizeChecker::MakeMemCopy. * add AllocVtcmWorkspace and FreeVtcmWorkspace * cleanup * Updated unittests to run all contrib/test_hexagon at CI. * create separate vtcm alloc lowering pass and transform * reset texture_flatten.cc * comments * CI bump * Fix lint formatting error. * Updated fix to remove StackSizeChecker entirely. * pass device and type to device api * Bugfix, verify the precheck's allocations, not own. * Bugfix, pass context information to the precheck. * pass order and shape to device api * working * fix up types and arg passing * pass scope to device api * common builtin for texture / vtcm * add scope to freend api * format and lint * fixed missed format error * restart ci * fix test random value issue + code review feedback * fix test hang * restructure lower vtcm pass per code review feedback (option a) * format error * global.vtcm + tvm_stack_make_shape Co-authored-by: Eric Lunderberg <[email protected]>
