Mark Mentovai 94a5a72efa mac: Tests that crash intentionally shouldn’t go to ReportCrash 
Crashpad has many tests that crash intentionally. Some of these are
gtest death tests, and others arrange for intentional crashes to test
Crashpad’s own crash-catching logic. On macOS, all of the gtest death
tests and some of the other intentional crashes were being logged by
ReportCrash, the system’s crash reporter. Since these reports
corresponded to intentional crashes, they were never useful, and served
only to clutter ~/Library/Logs/DiagnosticReports.

Since Crashpad is adept at handling exceptions on its own, this
introduces the “exception swallowing server”,
crashpad_exception_swallower, which is a Mach exception server that
implements a no-op exception handler routine for all exceptions
received. The exception swallowing server is established as the task
handler for EXC_CRASH and EXC_CORPSE_NOTIFY exceptions during gtest
death tests invoked by {ASSERT,EXPECT}_DEATH_{CHECK,CRASH}, and for all
child processes invoked by the Multiprocess test infrastructure. The
exception swallowing server is not in effect at other times, so
unexpected crashes in test code can still be handled by ReportCrash or
another crash reporter.

With this change in place, no new reports are generated in the
user-level ~/Library/Logs/DiagnosticReports or the system’s
/Library/Logs/DiagnosticReports during a run of Crashpad’s full test
suite on macOS.
