[turbofan] Fix UnifyReturn magic in the inliner.
...
The inliner previously assumed that there will only be returns reaching
the end node, but that's not true. This refactoring will make it
possible to also hook up Deoptimize, Throw and Terminate nodes reaching
end properly.

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.
