[PATCH] D34396: Adding code padding for performance stability - first policy (BranchesWithSameTargetAvoidancePolicy)

Removed unwanted dependencies introduces in my previous patch: MC layer no longer depends on CodeGen, Core or Target. This was achieved by introducing a new structure named MCCodePaddingContext that is being created by AsmPrinter and passed on to the MC layer (all the way to MCCodePadder). This replaces the direct use of TargetMachine, MachineBasicBlock, MachineFunction and MachineLoopInfo by the MCCodePadder.
Note: This time I used "svn diff -x -U999999" to create the patch, so comparison between this patch and the previous one may prove to be challenging (This had to be done for future work and review).
