It was an inline test before. Clang stopped emitting line information for the TLS initialization and the inline test didn't have a way to break before it anymore. This rewrites the test as a full-fldeged python test and improves the checking of the error case to verify that the failure we are looking for is related to the TLS setup not being complete.
