Patch enables support for float point math operations as base instructions for copyable elements. It also fixes some scheduling issues, found during testing Reviewers: hiraditya, RKSimon Pull Request: https://github.com/llvm/llvm-project/pull/169857 Recommit after reverts in 9008922707915a6632fb74ed301bce11d8775e2a and c2441689830fcb2588673dedba98da1219a2fb9e. c2441689830fcb2588673dedba98da1219a2fb9e was caused by other issues, not related to this patch directly
