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.

This patch adds several new tunables to control the behavior of
elision on supported platforms[1]. Since elision now depends
on tunables, we should always *compile* with elision enabled,
and leave the code disabled, but available for runtime
selection. This gives us *much* better compile-time testing of
the existing code to avoid bit-rot[2].
Tested on ppc, ppc64, ppc64le, s390x and x86_64.
[1] This part of the patch was initially proposed by
Paul Murphy but was "staled" because the framework have changed
since the patch was originally proposed:
https://patchwork.sourceware.org/patch/10342/
[2] This part of the patch was inititally proposed as a RFC by
Carlos O'Donnell. Make sense to me integrate this on the patch:

tst-mutex5 and 8 test some behaviour not required by POSIX,
that elision changes. This changes these tests to not check
this when elision is enabled at configure time.
