I agree.

Yes, in practice xfree doesn't do anything more than free. I looked
at the code, and it only contains a check against NULL, right now.
The C standard requires that free does nothing when passed a NULL
pointer.  So unless we're building GDB with a screwy C compiler,
it's strictly equivalent to calling free.

Still, I think it'd be nice to get rid of these. In desperate
situations, one might want to locally hack these to track memory
issues...
