[TSan][Linux] Fix libdispatch interception macros compilation errors

Authored by yln on Mar 6 2019, 6:24 PM.



Most libdispatch functions come in two variants: callbacks can be
specified via blocks or function pointers. Some of our interceptors for
the block variant actually forward to the function variant. However, on
Linux, DECLARE_REAL(name) has to appear before REAL(name).

This patch reorders _f variant interceptors before _b variants
where possible and forward declares the _f variant in the remaining
cases (cyclic dependency between _f and _b interceptors).

Also rename macro to DISPATCH_INTERCEPT_ASYNC_F for better consistency.
