Justin Holewinski 428cf0e49a [NVPTX] Improve handling of FP fusion 
We now consider the FPOpFusion flag when determining whether
to fuse ops.  We also explicitly emit add.rn when fusion is
disabled to prevent ptxas from fusing the operations on its
own.

Justin Holewinski a2a63d28df [NVPTX] Start conversion to MC infrastructure 
This change converts the NVPTX target to use the MC infrastructure
instead of directly emitting MachineInstr instances. This brings
the target more up-to-date with LLVM TOT, and should fix PR15175
and PR15958 (libNVPTXInstPrinter is empty) as a side-effect.
