nptl: Add test for callee-saved register restore in pthread_exit
GCC PR 83641 results in a miscompilation of libpthread, which causes pthread_exit not to restore callee-saved registers before running destructors for objects on the stack. This test detects this situation: info: unsigned int, direct pthread_exit call tst-thread-exit-clobber.cc:80: numeric comparison failure left: 4148288912 (0xf741dd90); from: value right: 1600833940 (0x5f6ac994); from: magic_values.v2 info: double, direct pthread_exit call info: unsigned int, indirect pthread_exit call info: double, indirect pthread_exit call error: 1 test failures
