[llvm] r203468 - Add test for LinkModules warning on triple, modified by r203009. Datalayout is already tested.

[Pete Cooper]

Hi JF

Similarly to the datalayout.ll test, this one is also triggering a failure on our GuardMalloc buildbot.  Would it be possible to check for something other than FileCheck being empty?

Thanks,
Pete
