- Changed the name of the flag to -enable-strict-reductions
- Removed unnecessary changes to create a mask as this was already handled by `VPReductionRecipe::execute`
- Simplified `checkOrderedReductions` for this patch. For now, if Exit is a Phi node we will not set `IsOrdered` to true.

- Removed `+sve` from the RUN line of the tests
- Added a negative test (`@fadd_multiple`)
- Added more tests
