[PATCH] D18069: Throttling LICM to reduce compile time of Value Propagation and Reg Splitting

[David Li via llvm-commits]

I have not read the patch in details, but it seems the main purpose of the patch to throttle LICM to reduce register pressure and the compile time benefit due to reduced LVI queries is just a good side effect of the patch? Do we have any performance data (runtime) showing the usefulness of the throttling?  (Whether this is the right approach to solve the spill problem is also subject to discussions).
