2717cc22 - [NVPTX] Merge consecutive elements while buffering constant vectors with sub-byte datatype. (#183628)

[NVPTX] Merge consecutive elements while buffering constant vectors with sub-byte datatype. (#183628) NVPTXAsmPrinter currently buffers one element at a time while generating PTX for constant global vectors. This causes an assertion when dealing with sub-byte datatype (like i4) since we allocate lesser buffer size. This PR fixes the printer to merge consecutive elements to form a full byte before buffering.
