102dfa8a - [DAGCombiner] Allow freeze to sink through fmul by adding it to AllowMultipleMaybePoisonOperands (#142250)

[DAGCombiner] Allow freeze to sink through fmul by adding it to AllowMultipleMaybePoisonOperands (#142250) Allow freeze to sink through fmul by treating it as a non-poison-generating op when operands are not poison. Adding `ISD::FMUL` to `AllowMultipleMaybePoisonOperands` lets DAG combine push freeze through fmul. This helps expose patterns like `fmul+fadd` for `FMA` fusion. When rebuilding the node, we drop flags like nnan/ninf/nsz that imply poison, but keep contract, reassoc, afn, and arcp. Closes: https://github.com/llvm/llvm-project/issues/141622
