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.

our non-C++11 bots, in which case I have to condition the change.  Testing.
