Added the patch and one of the tests in r181998.

As for the other test, adding it at the end of cxx11-thread-local.cpp 
results in a CHECK line failing to find its target. Since I know very 
little about llvm bytecode, I left this addition to someone more 
knowledgeable ... if you prefer, I can add those lines in their own test 
file.
