Improve robustness of dependency-generation-crash.c test.

MatzeB · MatzeB · commit e0fc8cabda04 · 2015-03-02T20:44:09.000Z
The test wants to provoke a failure when opening the output file. Using chmod 0 on the output file does not work reliably on all filesystems or when running the test as root. Change the test to use a nonexistant directory instead. Differential Revision: http://reviews.llvm.org/D7620 llvm-svn: 231009
