  [NVPTX] add support for encoding PTX registers for DWARF

This patch adds support for encoding PTX registers for DWARF, using the encoding supported by nvcc and cuda-gcc.

There are some other features still needed for proper register debugging that this patch does not address, such as DW_AT_address_class.
