Add runtime check if mutex will be elided in tst-mutex8 testcases.
An elided mutex don't fail destroy. Elision was disabled for the test nptl/tst-mutex8 in nptl/Makefile. Thus we can run tests which destroy a locked mutex. As elision is only disabled for tst-mutex8, the variants tst-mutex8-static, tst-mutexpi8 and tst-mutexpi8-static are still failing if lock elision is enabled. This patch adds a runtime check, if the checked type of mutex will be elided. This check is using TUNABLE_GET_FULL to determine if elision is enabled via the tunables framework. The pthread_mutex_destroy tests are only run if we dont't assume an elided mutex. This way, we can run the whole glibc testsuite with or without enabled lock elision. ChangeLog: * nptl/Makefile (tst-mutex8-ENV): Delete. * nptl/tst-mutex8.c (check_type): Add runtime check if mutex will be elided.
