Add support for remapping metadata kind IDs when reading in a
bitcode file, so that two bitcode files where the same metadata kind
name happens to have been assigned a different ID can still be
linked together.
Eliminate the restriction that metadata kind IDs can't be 0.
Change MD_dbg from 1 to 0, because we can now, and because it's
less mysterious that way.
