New Revision: 127928

URL: http://llvm.org/viewvc/llvm-project?rev=127928&view=rev
Log:
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.
