[NVPTX] Added a feature to use short pointers for const/local/shared AS. Const/local/shared address spaces are all < 4GB and we can always use 32-bit pointers to access them. This has substantial performance impact on kernels that uses shared memory for intermediary results. The feature is disabled by default.
