DAG: Fix getNode dropping flags if there's a glue output
The AMDGPU non-strict fdiv lowering needs to introduce an FP mode
switch in some cases, and has custom nodes to provide chain/glue for
the intermediate FP operations. We need to propagate nofpexcept here,
but getNode was dropping the flags.
Adding nofpexcept in the AMDGPU custom lowering is left to a future
patch.
Also fix a second case where flags were dropped, but in this case it
seems it just didn't handle this number of operands.
Test will be included in future AMDGPU patch.
