[PATCH v3 05/64] compiler: Tweak __UNIQUE_ID() naming

[Josh Poimboeuf]

In preparation for the objtool klp diff subcommand, add an underscore
between the name and the counter.  This will make it possible for
objtool to distinguish between the non-unique and unique parts of the
symbol name so it can properly correlate the symbols.
