[llvm] r195494 - Debug Info: add a constant for debug info version number.

[Eric Christopher]

Naming is hard, but I'd rather this not be in the Dwarf file and
rather in the IR files since this is entirely an IR thing and not
related to any actual dwarf constant at all.

DEBUG_METADATA_VERSION might be a better name.
