This adds new code stubs for abstract relational comparison, namely LessThanStub, LessThanOrEqualStub, GreaterThanStub and GreaterThanOrEqualStub, and hooks them up for Ignition and TurboFan. These stubs implement the full compare operation without any unpredictable bailouts. Currently they still go to C++ for string comparisons, and also use the %ToPrimitive_Number runtime entry, as we still lack a stub for the ToPrimitive operation. These issues will be addressed separately in follow-up CLs. Drive-by-fix: Add support for deferred code in the RawMachineAssembler and CodeStubAssembler. A block can be marked as deferred by marking its Label as deferred, which will then make the register allocator penalize this block and prefer better register assignments for the other blocks.
