	auto-diff results (#5394) * Various AD enhancements * Fix issue with pt-loop test * Update pt-loop.slang * More fixes for perf. Final minimal context test now passes. * Fix issue with loop-elimination pass not running after dce * Try fix wgpu test by removing select operator * Disable wgpu * Delete out.wgsl * Remove comments * Update slang-ir-util.cpp * Fix header relative paths for slang-embed * Disbale wgpu for a few other tests * Better way of determining which params to ignore for side-effects * Update slang-ir-dce.cpp * Fix issue with circular reference from previous AD pass being left behind for the next AD pass * Update slang-ir-dce.cpp

2023-02-09	Reverse-mode Loop Support (#2635)	Sai Praveen Bangaru
	* Full loop support now working. MaxItersAttr in progress * Lookup table updates? * Fixed the max iters decoration * Minox fixes & remove superfluous code * fixup warnings * Revert "Lookup table updates?" This reverts commit 7d9b0793fb5239f31d1155776e846dcf1892d8d9. * Update 07-autodiff.md * Change maxiters to MaxIters * Added asserts * Update 07-autodiff.md
2023-02-03	Overhaul `transposeParameterBlock` to support `inout` params. (#2621)	Yong He
	* Overhaul `transposeParameterBlock` to support `inout` params. * Small bug fixes. * Bug fix on differentiable intrinsic specialization. * Fixes. * Run autodiff tests on CPU. * Clean up. * More bug fixes., * Add test coverage on inout param. * Fix language server hinting for transcribed mutable params. --------- Co-authored-by: Yong He <yhe@nvidia.com>
2023-01-30	Overhauled reverse-mode control flow handling (#2608)	Sai Praveen Bangaru
	* Added switch-case support; fixed non-diff parameter transposition * Made region propagation much more robust. Partial loop unzip implementation * WIP: Added most loop handling code, and a test. Still untested * Added CFG Normalization pass + CFG Reversal Pass + Loop Unzipping + most loop transcription * Add single-iter-loop test. * proj files * removed comments * Update reverse-loop.slang * Removed out-of-date code * Disabled IR validation during constructSSA phase of normalizeCFG. constructSSA now reuses sharedBuilder * Moved normalizeCFG() call to prepareFuncForBackwardDiff()
