           Summary: MultiSource/Applications/spiff needs 1.2G virtual
                    memory, crashes with ulimit 300

RunSafely sets a 300MB ulimit -v, and this causes
MultiSource/Applications/spiff to crash on x86-64.

If I change the limit to 1200000, the test passes.
This is not a regression if we look at the behavior: in LLVM 2.6 it has run out
of memory too on all configurations, including native:
Out of Memory
exit 2

The difference is that now we crash when running out of memory, so I don't
think this is a release blocker.

Something should be done for llvm 2.8, either make this test use less memory,
or increase the limit in RunSafely.
