Add a TurboFan skeleton for StringAddStub.

Currently the stub simply calls out to the runtime, this will be
improved in a later CLs. The current state at least avoids bit-rot and
later merging horror.

Fixes frame construction logic for stubs, too, and contains quite a few
tiny cleanups in stub-land.

Avoid excessive GCs in small heaps.

Small heaps and small heap growing factor can lead to excessive GCs in corner cases.

Consider function F(old_gen_size, factor) that returns the number of bytes that
have to be allocated in the old generation to start incremental marking.

F(4MB, 1.1) = 4MB (because of kMinimumOldGenerationAllocationLimit)
F(6MB, 1.1) = 2MB (because of kMinimumOldGenerationAllocationLimit)
F(8MB, 1.1) = 800KB

Funtion F should be monotonic in old_gen_size, but it currently has a minimum
at kMinimumOldGenerationAllocationLimit.

This CL makes F monotonic.

[turbofan] Carefully update frame states during inlining.

During inlining we should pay attention to only rewire the outer frame
states of the inlinee, but leave any inner frame states of the inlinee
untouched. Otherwise we might run into trouble once we start caching
graphs, or do getter/setter inlining.
