This patch disables the FSUB(-0,X)->FNEG(X) DAG combine when we're flushing subnormals. It requires updating the existing AMDGPU tests to use the fneg IR instruction, in place of the old fsub(-0,X) canonical form, since AMDGPU is the only backend currently checking the DenormalMode flags. Note that this will require follow-up optimizations to make sure the FSUB(-0,X) form is handled appropriately Differential Revision: https://reviews.llvm.org/D93243
