Don't track depfiles as result files which need to be cleaned up on failure.
...
This is a partial revert of r143846. While cleaning up after a crash is
probably a good idea, we were also deleting .d files if the compilation failed
due to invalid input, which is not the desired behavior. The test is XFAIL'd
until the cleanup code can be reworked to do the right thing.
