	This commit removes unnecessary Load and Store pairs in IR. When the IR is like ``` let %1 = var let %2 = load(%ptr) store(%1 %2) ``` This PR will replace all uses of %1 with %ptr. And the load and store instructions will be removed. But I found that there can be cases where %2 might be still used later in other IRs. For these cases, the removal of load instruction relies on DCE. --------- Co-authored-by: slangbot <ellieh+slangbot@nvidia.com>
2025-08-07	Initial copy elision pass (#8042)	ArielG-NV
	Fixes #7574 Changes: * Add an initial (fairly simple) optimization pass which is able to eliminate redundant copies. * Our current existing optimizer passes remove redundant load/store very robustly, this pass will focus on other cases of copy elimination * Primary approach is to make all functions which are `in T` and `T` is trivial to copy into a `__constref T`. We then (depending on scenario) manually insert a variable+load if a pass-by-reference is not possible; otherwise we pass by `constref`. * Added optimizations to eliminate redundant code which causes `constref` to fail to compile --------- Co-authored-by: Harsh Aggarwal <haaggarwal@nvidia.com> Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: slangbot <ellieh+slangbot@nvidia.com> Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com>
