[Piglit] [PATCH 18/18] framework: Handle crashing subtest.

[Fabian Bieler]

Piglit silently ignored crashes in subtests.

It's impossible to know what subtest crashed. Theoretically it might
even be possible that a test crashes after the last call to
piglit_report_subtest_result and thus no subtest crashed. Though the
odds of that happening are probably pretty long.

If a test with subtests crashes, this commit adds an additional subtest
named "unknown" with result "crash".

The issue that subsequent subtests are not run is not touched upon by
this commit.

This is more of a work-around. A proper fix would modify the C subtest
framework to print a list of subtests it intends to run at the start of
the test. This would enable the python subtest framework to know which
subtest crashed.
But that's a lot of work (it would require modifying more than 100
tests) and this is better than nothing.
