PR Overview
This PR fixes the MultiplyAddEstimate implementation for integer types by updating both the test cases and the low‐level implementation details.
- Updated tests to use T.MultiplyAddEstimate instead of T.FusedMultiplyAdd.
- Added a new suite of tests for Span, Span, Span destination scenarios.
- Adjusted type checks in the MultiplyAddEstimate implementation to better differentiate float handling.
