With this fix codegen looks like:

mov ecx,[eax+0xf]  ;;; <@52,#38> load-named-field
add ecx,0x2  ;;; <@54,#40> add-i
mov [eax+0xf],ecx  ;;; <@56,#41> store-named-field

without it there is an overflow check and jump to deopt.

x64 code looks similar, except there is an (annoying) smi-untag then int32-to-smi around the add operation.

(1) default: semi-automated
(2) manual (-m option), like in the old script
(3) forced (-f option), no user input required no editor check

The class added unecessary level of indirection to the heap profiler implementation. I merged some of its implementation into HeapProfiler and deleted the rest. This refactoring is also a prerequisite for keeping HeapObjectsMap alive even when all snapshots are deleted.

Original commit message:
Previously BinaryOpIC and BinaryOpStub were pretty much interdependent.
However, in order to use allocation sites for string adds on-demand,
we need to be able to use different stubs (with a different number of
register parameters, via trampolines) depending on the BinaryOpIC state.

The test in question (test-debug/LiveEditEnabled) is expected to fail, and it
failed, but because of the wrong reason (the test asserts that the default
isolate is not initialized, SetLiveEditEnabled initialized the default
isolate because it doesn't get one as param). Now it fails because of the right
reason.
