[LLVMdev] FYI: Changing RunSafely.sh to only track user time

[Daniel Dunbar]

I am going to change the LLVM test-suite RunSafely.sh to only track
'user' time, instead of reporting 'user' + 'sys' time as it currently
does. This will probably cause a spike in nightly test numbers,
although hopefully it will be limited to the smaller tests.

The eventual goal is to report all numbers (independently), so that we
can control for noise better. However, until that happens it is better
to track the most stable & interesting number.
