Reviewers: Jakob, Description: Simplify stack check instruction in Crankshaft.
So far we had two types of stack checks: one used for function entries and one used at loop back edges which uses a deferred code object to avoid spilling of registers in the loop. After refactoring lazy deoptimization the first stack check can also use deferred code. This change removes the first type of stack check instruction in Crankshaft and uses a deferred stack check in all places.
