Nico Weber b3a3522ac1 Add functions to save and restore the PrettyStackTrace state. ... PrettyStackTraceHead is a LLVM_THREAD_LOCAL, which means it's just a global in LLVM_ENABLE_THREADS=NO builds. If a CrashRecoveryContext is used with code that uses PrettyStackEntries, and a crash happens, PrettyStackTraceHead is currently not reset to its pre-crash value. These functions make it possible to add a cleanup to such code that does this. (Not reseting the value then causes the assert in ~PrettyStackTraceEntry() to fire if the code outside of the CrashRecoveryContext also uses PrettyStackEntries -- for example, clang when building a module.)
