George Burgess IV aea6ade63a Make incomplete type errors better with enable_if
This patch fixes the order in which we evaluate the different ways that
a function call could be disallowed. Now, if you call a non-overloaded
function with an incomplete type and failing enable_if, we'll prioritize
reporting the more obvious error (use of incomplete type) over reporting
the failing enable_if.

Thanks to Ettore Speziale for the patch!

Nick Lewycky 36e9b3ccff Neither attribute overloadable nor enable_if are supported by GCC. Disable the
GCC warning about attributes on function definitions for both of them.

Nick Lewycky 35a6ef4c35 Add a new attribute 'enable_if' which can be used to control overload resolution based on the values of the function arguments at the call site.
