Filip Pizlo 67d9709341 Make PrettyStackTraceEntry use ManagedStatic for its ThreadLocal. ...

This was somewhat tricky because ~PrettyStackTraceEntry() may run after 
llvm_shutdown() has been called. This is rare and only happens for a common idiom 
used in the main() functions of command-line tools. This works around the idiom by 
skipping the stack clean-up if the PrettyStackTraceHead ManagedStatic is not 
constructed (i.e. llvm_shutdown() has been called).
