41800386f1 [NVPTX] Handle addrspacecast constant expressions in aggregate initializers 
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.
