cdf9bf7048 make/clang_darwin: Tweak CheckArches function to force the integrated-as and use 
the stub SDK to try and ensure we always pick up the right archs when they
should be able to be used.
 - Also, warn when we drop an architecture.

This is a reapplication of r150232 that should stick now that we have the
integrated assembler on for ARM.

7e07f56811 Introduce __asan_set_error_report_callback() to allow the client program post-process the error reports. 
If the callback is set, Report() and Printf() print the reports into a buffer (together with stderr), which is then passed to the client.

0be25d562c Check that the FakeStack size is non-zero before looking into it. 
Sometimes DescribeStackAddress is called before another thread's FakeStack is initialized, which could previously cause a check to fire.
