Addressed comments. Added support for merging instructions in X86FrameLowering::mergeSPUpdate() when CFI are present.

Does this solution look good?

Removed copying CFI Instructions via copy constructor.

Ok, then I would suggest that instead of this code we
- make CFI instructions duplicable;
- let TailDuplicator::shouldTailDuplicate return false for CFI and Darwin,
or better yet -
- fix generateCompactUnwindEncoding in ARM, AArch64 and x86 backends to fallback to DWARF when the info cannot fit into compact encoding.

The idea behind this code is to fix Linux (which uses DWARF) and leave Darwin (which uses compact-unwind) as-is. That's why nonDuplicableInstruction returns true if (MBB->getParent()->getTarget().getTargetTriple().isOSDarwin()).
