Removing old CMake build system

[jlpeyton]

Summary

I'm going to be sending a series of patches to update/improve the cmake build system to the llvm standard.

I've just deleted the old cmake build system entirely. It doesn't work anymore and it makes sense to have only one CMake build system.

So that it's clear to me, runtime/CMakeLists.txt is the "new" CMake build and will be receiving updates?

runtime/CMakeLists.txt has been the primary CMake build system for a while. It will be receiving all the updates.
