Greg Clayton bde0a1632b Added the ability to dump hex bytes easily into a raw_ostream. 
Unit tests were added to verify this functionality keeps working correctly.

Example output for raw hex bytes:
llvm::ArrayRef<uint8_t> Bytes = ...;
llvm::outs() << format_hex_bytes(Bytes);
554889e5 4881ec70 04000048 8d051002
00004c8d 05fd0100 004c8b0d d0020000

Example output for raw hex bytes with offsets:
llvm::outs() << format_hex_bytes(Bytes, 0x100000d10);
0x0000000100000d10: 554889e5 4881ec70 04000048 8d051002
0x0000000100000d20: 00004c8d 05fd0100 004c8b0d d0020000

Example output for raw hex bytes with ASCII with offsets:
llvm::outs() << format_hex_bytes_with_ascii(Bytes, 0x100000d10);
0x0000000100000d10: 554889e5 4881ec70 04000048 8d051002 |UH.?H.?p...H....|
0x0000000100000d20: 00004c8d 05fd0100 004c8b0d d0020000 |..L..?...L..?...|

The default groups bytes into 4 byte groups, but this can be changed to 1 byte:
llvm::outs() << format_hex_bytes(Bytes, 0x100000d10, 16 /*NumPerLine*/, 1 /*ByteGroupSize*/);
0x0000000100000d10: 55 48 89 e5 48 81 ec 70 04 00 00 48 8d 05 10 02
0x0000000100000d20: 00 00 4c 8d 05 fd 01 00 00 4c 8b 0d d0 02 00 00

llvm::outs() << format_hex_bytes(Bytes, 0x100000d10, 16 /*NumPerLine*/, 2 /*ByteGroupSize*/);
0x0000000100000d10: 5548 89e5 4881 ec70 0400 0048 8d05 1002
0x0000000100000d20: 0000 4c8d 05fd 0100 004c 8b0d d002 0000

llvm::outs() << format_hex_bytes(Bytes, 0x100000d10, 8 /*NumPerLine*/, 1 /*ByteGroupSize*/);
0x0000000100000d10: 55 48 89 e5 48 81 ec 70
0x0000000100000d18: 04 00 00 48 8d 05 10 02
0x0000000100000d20: 00 00 4c 8d 05 fd 01 00
0x0000000100000d28: 00 4c 8b 0d d0 02 00 00

DebugInfo Switch all DWARF variables for tags, attributes and forms over to use the llvm::dwarf enumerations instead of using raw uint16_t values.
