glsl/parser: Move anonymous struct name handling to the parser

There are two callers of the constructor, and they are right next to
each other.  Move the "#anon_struct" name handling to the parser so that
the conditional can be removed.

I've also deleted part of the comment (about the memory leak) because I
don't think it's quite accurate or relevant.
