Siva Chandra Reddy 5e61b9c556 [libc][NFC] Make all integration tests depend on the threads implementation.
The integration tests use the loader which sets up the main thread's
self object. So, all integration tests have to depend on the threads
implementation.

Siva Chandra Reddy 9b9ff63b03 [libc][NFC] Make thread_detach_test an integration test.
This is simple switch from a unittest to an integration test. It is
being done as a preparatory step to adding TLS support to thread
creation. TLS setup and initialization is tightly coupled with the
loader and hence all thread related tests should be integration tests.

Siva Chandra Reddy badda4ac3c [libc] Linux threads - Set CLEAR_TID addr to 0 when exiting a detached thread.
A detached thread cleans itself up at completion. So, the CLEAR_TID memory is
also gone by the time the kernel tries to signal potential waiters. By nulling
the CLEAR_TID address, we prevent the kernel from signalling at a non-existent
futex location.

Previosly, a pointer to the thread data structure was stored in the

lifetime of the thread. On the the other hand, thread attributes are
stored on the thread stack so they live as long as the thread lives.

Alex Brachet a442c62888 [libc] Make div test names unique
In Fuchsia, all tests in a directory, ie stdlib, are linked
into one executable, this causes problems for multiple
definitions of the vtables of the div tests because their
class has the same name. This patch just trivially changes

Kirill Okhotnikov fdf1fda5a8 [libc][math] Improved ExhaustiveTest performance.
Previous implementation splits value ranges around threads. Because of
very different performance of testing functions over different ranges,
CPU utilization were poor. Current implementation split test range
over small pieces and threads take the pieces when they finish with
previous. Therefore the CPU load is constant during testing.
