Add an additional test of TLS variables, with different alignment, accessed from different modules. The idea of the alignment test is similar to tst-tlsalign and the same code is shared for setting up test variables, but unlike the tst-tlsalign code, there are multiple threads and variables are accessed from multiple objects to verify that they get a consistent notion of the address of an object within a thread. Threads are repeatedly created and shut down to verify proper initialization in each new thread. The test is also repeated with TLS descriptors when supported. (However, only initial-exec TLS is covered in this test.) Tested for x86_64.
