Roll clang 305735:307486.
This includes a change to the compiler that removes the ability to
suppress availability warnings by redeclaring functions. The new way
to suppress warnings is to enclose the function reference in an
"if (@available)" block.
Previous CLs have cleaned up the code base to use the new way of
suppressing warnings (see bug).
