6fc00b4dea Fix out-of-bounds read in SourcePositionToScriptPosition with --hydrogen-track-positions. 
We were indexing into the list of inlined functions with inlining ID, which is incorrect.

There can be multiple inlinining IDs corresponding to the same inlined function, because inlining ID is inlining path sensitive unique id for an inlining attempt.

Additionally allow HAbnormalExit to have unknown source position even if we are tracking source positions. No code is generated from abnormal exits anyways.

a4176d2052 Removing ic.h from code-stubs.h 
CodeStubs use state types defined in ic.h, but this has the unfortunate effect of spreading ic.h all over the place. Instead, define these shared state types in ic-public.h and allow ic.h to concern itself with internal state change of the ICs.

More work could/should be done here, but this is a first step.

6d3fc8a322 Introduce FLAG_vector_ics. 
When FLAG_vector_ics is true, then AST nodes that use Load and KeyedLoad ICs
will allocate a type vector slot to store feedback information. Full codegen
will emit a load of the slot into a register if the flag is on.

Support is incomplete, right now the IC doesn't know how to use the feedback
slot.

018ef484b9 More OStreamsUse OStreams more often. 
This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

71789ea1e5 Reland r20974: Unify and simplify the FastCloneShallowArrayStub 
- Don't bake in length/capacity into full codegen calls of stubs,
allowing boilerplates to increase their capacity without regenerating
code.
- Unify all variants of the clone stub into a single,
length-independent version.
- Various tweaks to make sure that the clone stub doesn't spill and
therefore need an eager stack frame.
- Handle all lengths of array literals in the fast case.

3e08756fa5 Fix new space array check limit. 
Also inline BuildNewSpaceArrayCheck() into its caller, because
the name BuildNewSpaceArrayCheck was confusing anyway, since
it has nothing do with new space actually.

a3fed0af84 Fix constructors for HLoadNamedField. 
Also try to determine an appropriate HType for tracked fields,
instead of (incorrectly) using HType::NonPrimitive() everywhere.

785bdf7c1e Don't add code dependencies eagerly for HCheckMaps. 
Instead of adding code dependencies on stable during
graph creation, we now add them during code generation
for those HCheckMaps that survived dead code elimination.
