We overload the `call` instruction with a macro, but it would misbehave when
the macro argument wasn't a valid identifier. Fix it by explicitly checking
if the argument is an identifier.

Bump the date in the header to 2017 as well. That was done in x264 as
part of an earlier commit but might as well squash it into this one.
