[test-suite] r262306 - lit: Add simple codesize module

[Matthias Braun via llvm-commits]

patches welcome (sorry I couldn't resist).

This commit was meant to demonstrate how additional metrics can be collected and that the infrastructure is there. I hope that fine grained metrics will be added over time. I have no plans myself yet at the moment to figure out what metrics are actually useful, testing it on different targets making sure we don't fail when llvm-size is not in the PATH...
