This change provides __restore/__restore_rt on x86 and __restore_rt on
x86_64 with unwinding information to be able to unwind through signal
frame via libgcc provided unwinding interface. See comments inlined for
more details.
Also remove the test that had a dependency on
__attribute__((cleanup(foo_cleanup))). It doesn't provide us with any
better test coverage than we have from the newer tests, and it doesn't
work well across a variety architectures (presumably because no one uses
this attribute in the real world).
Tested this on host via bionic-unit-tests-run-on-host on both x86 and
x86-64.

There is a known bug running clone with the CLONE_VM flag, so for host
create an empty test.
Change the expected output of the stdio test for a glibc difference.
Change the pause test to use ScopedSignalHandler to setup/restore the SIGALRM
handler.
After this, running bionic-unit-tests-glibc passes for all tests.
