We need to track if an AddrSpaceCast expression was seen when
generating an MCExpr for a ConstantExpr. This change introduces a
custom lowerConstant method to the NVPTX asm printer that will create
NVPTXGenericMCSymbolRefExpr nodes at the appropriate places to encode
the information that a given symbol needs to be casted to a generic
address.

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.
