NVPTXAliasAnalysis extends the default AA to take pointer address spaces 
into account. The analysis assumes that pointers in different address
spaces do not alias, unless one of them is generic (flat) address
space.

The patch also implements pointsToConstantMemory() to expose semantic
of the constant address space to the optimizer as discussed in
D112466 <https://reviews.llvm.org/D112466>.
