There are sure to be many places where a buffer of bytes need to be dumped in LLVM. This change allows users to quickly dump a buffer of bytes with optional offset prefix and ASCII display:

Example output for raw hex bytes:
55 48 89 e5 48 81 ec 70 04 00 00 48 8d 05 10 02
00 00 4c 8d 05 fd 01 00 00 4c 8b 0d d0 02 00 00

Example output for raw hex bytes with ASCII:
55 48 89 e5 48 81 ec 70 04 00 00 48 8d 05 10 02  UH.?H.?p...H....
00 00 4c 8d 05 fd 01 00 00 4c 8b 0d d0 02 00 00  ..L..?...L..?...

Example output for raw hex bytes with ASCII and offsets/addresses:
0x100000d10: 55 48 89 e5 48 81 ec 70 04 00 00 48 8d 05 10 02  UH.?H.?p...H....
0x100000d20: 00 00 4c 8d 05 fd 01 00 00 4c 8b 0d d0 02 00 00  ..L..?...L..?...

Added unit tests as well.
