3215645b - [AMDGPU] Enable scheduler mfma rewrite stage by default (#180751)

[AMDGPU] Enable scheduler mfma rewrite stage by default (#180751) After performance testing, it was determined that the large number of copies that are inserted outside the loop are more than offset by better allocation within the loop as a result of the rewrite. Additionally, there is a minor cleanup of the cost logic. --------- Co-authored-by: Tony Linthicum <tlinthic@gmail.com>
