In addition:
  - optionally add global flag to capture compile intent for UAR:
    __asan_detect_use_after_return_always.

Francis Ricci 42175cb0d7 Add lsan interceptors for libdispatch functions on darwin 
Summary:
This is required for standalone LSan to work with libdispatch worker threads,
and is a slimmed down version of the functionality provided for ASan
in asan_mac.cc.

Re-commit of r305695 with use_stacks=0 to get around a racy lingering pointer.

Francis Ricci ff567a8ba2 Enable weak hooks on darwin 
Summary:
By default, darwin requires a definition for weak interface functions at
link time. Adding the '-U' link flag with each weak function allows these
weak interface functions to be used without definitions, which mirrors
behavior on linux and windows.
