ac146c4820 [nvFuser] Switching to CudaFusionGuard from BailOut for nvfuser - update 2 (#46452)
Summary:
1. Added CudaFusionGuard as the custom TypeCheck for nvfuser; enabled dynamic shape support with profiling executor;
2. dropped support for legacy fuser;
3. re-enabled nvfuser tests;
4. added registration for profiling record to allow profiling on user specified nodes.

99e0a87bbb [nvFuser] Latency improvements for pointwise + reduction fusion (#45218)
Summary:
A lot of changes are in this update, some highlights:

- Added Doxygen config file
- Split the fusion IR (higher level TE like IR) from kernel IR (lower level CUDA like IR)
- Improved latency with dynamic shape handling for the fusion logic
- Prevent recompilation for pointwise + reduction fusions when not needed
- Improvements to inner dimension reduction performance
- Added input -> kernel + kernel launch parameters cache, added eviction policy
- Added reduction fusions with multiple outputs (still single reduction stage)
- Fixed code generation bugs for symbolic tiled GEMM example
- Added thread predicates to prevent shared memory form being loaded multiple times
- Improved sync threads placements with shared memory and removed read before write race
- Fixes to FP16 reduction fusions where output would come back as FP32
