[llvm] r315870 - Phony change to CMakeLists.txt to (hopefully) trigger regeneration

[Krzysztof Parzyszek via llvm-commits]

The problem was that cmake would not re-run to update the Makefiles (or 
ninja equivalents). If I just deleted the CFIVerifyTests executable, 
ninja would still rebuild it.

I tried to "touch CMakeCache.txt" on the Hexagon bots, but even that 
didn't cause cmake to reconfigure. I had to remove the contents of the 
build directory to finally get the bot to turn green.

There should be an option to force a completely clean build, this is not 
the first time we've had this kind of a problem.
