Behdad Esfahbod 509353357c [iter] Use hb_declval() instead of Null() to get instance
I had used Null to make one of the bots happy before.  Not going
to bend to such demands anymore..

Behdad Esfahbod 6b6783e158 [iter/meta] Fix build on newer clang
The mystery failure had to do with SFINAE failure because the template
function involved was accessing ::iter_t of a type that was also named iter_t.
In this context, apparently:

warning: ISO C++ specifies that qualified reference to 'iter_t' is a
constructor name rather than a type in this context, despite preceding 'typename' keyword
[-Winjected-class-name]

We use a new macro, also called hb_iter_t(), to get iterator type of
a type.  This uses declval/hb_decltype, and has the added benefit
that it returns correct type for const vs non-const objects, if they
have different iterators.

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.

Behdad Esfahbod cb5011d364 Revert "[iter] Add hb_iter_of_t<>"
This reverts commit d6cbe96e2fc7bc8f1c10e631b52b1ef31ff9a6f5.

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