    - Improve the HLSL legalization optimization recipe. #1311
  - Optimizer:
    - General speedups.
-   - Improve folding, including coverage for floating point and OpSelect.
+   - Remove generic dead code elimination functionality from transforms:
+       --eliminate-local-single-block
+       --eliminate-local-single-store
+       --eliminate-local-multi-store
+     To recover the previous behaviour, a recipe using those transforms should now
+     also invoke the --eliminate-dead-code-aggressive transform.
+   - Improve folding, including coverage for floating point, OpSelect, and arithmetic
+     with non-trivial constant operands.
    - Add loop-invariant code motion pass.
    - Add loop-unrolling pass, for honouring unroll hits.
    - Add loop-unswitch pass.
