8ebf3993d6 Record ToBoolean's type information in Hydrogen's HBranch instruction, so we can use it in LCodeGen::DoBranch later.

0ff690b370 Fixed a long-standing TODO: Removed a few *-incl.h #includes from isolate.h. 
ZoneAllocationPolicy::New is not inlined anymore because this pulls in far too
much stuff and doesn't really make any measurable performance difference. And
no, the #includes are still not in alphabetical order... ;-)

af24067fa5 Refactor the way we collect the information for associating type-related infos 
with AST IDs. Previously 3 different places had to match in how they handle a
given case, now we are down to 2, with an even simpler logic.

The downside is that due to this simpler logic the allocated dictionary could be
larger than before, but test have shown that this happens *very* rarely, because
its capacity is rounded to the next power of 2, anyway. Furthermore, the oracle
doesn't live long enough that we should really care.

The whole oracle is probably still a bit too tricky in its details, but this is
at least a step into the right direction.

dc47de6732 Distinguish keyed loads with a symbol key from fast elements loads. 
This change fixes the deoptimization when a keyed load is used with
a symbol key. Before we would wrongly generate a fast elements load.
Now we generate a generic keyed load instead.

6f775f2fb0 Fix calls of strict mode function with an implicit receiver. 
Only IA32 version for now. I'll start porting.

Strict mode functions are to get 'undefined' as the receiver when
called with an implicit receiver. Modes are bad! It forces us to have
checks on all function calls.

This change attempts to limit the cost by passing information about
whether or not a call is with an implicit or explicit receiver in ecx
as part of the calling convention. The cost is setting ecx on all
calls and checking ecx on entry to strict mode functions.

Implicit/explicit receiver state has to be maintained by ICs. Various
stubs have to not clobber ecx or save and restore it.

CallFunction stub needs to check if the receiver is implicit when it
doesn't know from the context.

5cd715cbc3 A tiny contribution for the IWYU day: Include allocation.h in every 
header which uses BASE_EMBEDDED and/or AllStatic. Note that still only
45 out of 135 headers in src/ can be used stand-alone, but at least
this is a little bit more than before...

9cca7d2733 Combine typed and pixel arrays. 
Worth mentioning:
- Specialized versions of pixel array and store/loads inside the generic stubs have been removed, since to have parity for all external arrays, 8 different versions would have to be inlined/checked.
- There's a new constant in v8.h for external arrays with pixel array elements.

11a4cb5718 Introduce extra IC state to record additional feedback from IC-s. 
Extra IC state is only two bits and only supported for call IC-s for
now. To change its extra state an IC stub jumps to a new miss stub
that goes to runtime as usual but then instead of going megamorphic
generates a monomorphic stub with the updated state.
