Ted Kremenek 857e535520 Properly initialize all fields in CrashReporterCleanupContext. This caused the buildbot failure earlier.

Ted Kremenek 9931652775 Temporarily stop recovering resources in CrashRecoveryContext while I investigate further why this works on my machine and not on others.

Ted Kremenek ab1a242ead Provide a means for CrashRecovery clients to determine if code is currently running while crash recovery cleanups are being processed.

Ted Kremenek 32aea2e401 Tweak CrashRecoveryContextCleanup to provide an easy method for clients to select between 'delete' and 'destructor' cleanups, and allow the destructor of CrashRecoveryContextCleanupRegister to be pseudo re-entrant.

Ted Kremenek 794a0714ad Tweak CrashRecoveryContext::GetCurrent() to return quickly if 'gCrsahRecoveryEnabled' is false. This avoids us needing to go to thread local storage for
the performance sensitive case where we are compiling code.

Ted Kremenek c44d3cf581 Augment CrashRecoveryContext to have registered "cleanup" objects that can be used to release resources during a crash.

Daniel Dunbar f4d90ba9f5 CrashRecoveryContext: Add RunSafelyOnThread helper function.

Daniel Dunbar 418e7046f7 CrashRecoveryContext: Add missing return, so that the signal fires after we our
routine is off the stack. Otherwise we show up rather confusingly in the stack
trace.

Daniel Dunbar 09b0c78918 CrashRecovery: Clear the current context on the first crash, to avoid re-entering it if the cleanup code crashes.

Daniel Dunbar b30266ed20 CrashRecovery: Add CrashRecoveryContext::GetCurrent(), so clients can find the active context from anywhere.

Daniel Dunbar ff329942cd CrashRecovery: Make CrashRecoveryContext static methods thread safe.

Daniel Dunbar 9789f81eb4 Make sure to include config.h, to pickup LLVM_ON_WIN32.

Daniel Dunbar af77e22b36 CrashRecoveryContext: Add a simple POSIX implementation.
- This works, but won't handle crashes on stack overflow, or signals delivered
   to a thread other than the one that crashed. The latter is particular annoying
   on Darwin, because SIGABRT tends to go to the main thread.

Daniel Dunbar 19a3b37441 Support: Add CrashRecoveryContext helper object.
- Designed as a simple wrapper to allow clients to attempt to catch crashes
   (memory errors, assertion violations, etc.) and do some kind of recovery.

 - Currently doesn't actually attempt to catch crashes.
