RosieSumpter added a comment.

- Added a check that the reduction phi isn't one of the multiply operands of fmuladd to `RecurrenceDescriptor::isRecurrenceInstr`
- Added a test case to strict-fadd.ll for the above
- Used initializer list instead of `SmallVector<> FMulOps` when creating FMul VPInstruction
- Simplified assert in `LoopVectorizationPlanner::adjustRecipesForReductions`
