Cameron McInally 31c7a2fd5c [FPEnv] Don't transform FSUB(-0,X)->FNEG(X) in SelectionDAGBuilder. ...

This patch stops unconditionally transforming FSUB(-0,X) into an FNEG(X) while building the DAG. There is also one small change to handle the new FSUB(-0,X) similarly to FNEG(X) in the AMDGPU backend.
