Behdad Esfahbod 7987095e64 [meta] Remove hb_enable_if_t 
It was only used for C++<11 which does not allow default parameters
in function templates.  Looks like we cannot support <11 anyway, so,
start cleaning up.

Behdad Esfahbod 15a6928436 [iter] Implement operator-> unconditionally 
The right condition to check for would have been "is_struct", which
we don't have.

Behdad Esfahbod f78f837ef1 [iter] Use aliasing using for types 
Fix ambiguity of hb_sorted_array_t::item_t with gcc.  No idea if that's a gcc bug
or what spec requires, but using aliasing using seems to fix it.  It probably breaks
our non-C++11 bots, in which case I have to condition the change.  Testing.

This reverts commit d6cbe96e2fc7bc8f1c10e631b52b1ef31ff9a6f5.

Isn't useful, as duplicate inheritance of same type results in ambiguity
errors...
