      [ic][ia32][x87] Don't push/pop value/slot/vector in store handlers. · 49695346
      ishell authored 
      According to new store IC calling convention the value, slot and vector are passed
on the stack and there's no need in trying to preserve values or respective registers
in store handlers.

Nice bonus: we also don't need virtual registers anymore.

      [stubs] Port SubStringStub to TurboFan · 49be3192
      jgruber authored 
      This ports the platform-specific SubStringStub to TurboFan.

It also contains a minor bug-fix for the case when the requested substring
length equals the subject string length, but the start index is not equal to 0.
The old stub implementation returned the subject string, while the new
implementation calls into runtime, which finally results in a thrown exception.

      [stubs] Port StoreTransitionStub and ElementsTransitionAndStoreStub to TurboFan. · 130d9893
      ishell authored 
      This CL also cleans up related interface descriptors:
1) unused StoreTransitionDescriptor is removed and VectorStoreTransitionDescriptor is
renamed to StoreTransitionDescriptor.
2) on ia32/x87 architectures slot and vector are passed on the stack (dispatcher/handlers
cleanup will be addressed in a separate CL).

These two stub ports have to be combined in one CL because:
1) without changing the StoreTransitionDescriptor TF was not able to compile them
on ia32/x87 (because of lack of registers),
2) it was not possible to change the descriptor first because Crankshaft was not able
to deal with the stack allocated parameters in case of a stub failure.

      Record call counts also for megamorphic calls. · 2ab3fcf4
      mvstanton authored 
      To make better inlining decisions, it's good to have call counts for poly/mega-morphic cases. This CL makes it work for calls, and another will follow to better unify the code between constructor calls and normal calls (and thence, to record megamorphic call counts there as well).

      Move kMaxRegularHeapObjectSize into globals · 059b5643
      mlippautz authored 
      This way we avoid the cyclic dependency between objects.h and heap.h and still
have one definition. Add a static assert that this size is indeed smaller than
the payload of a page.

Follow ups can finally remove the dependency on spaces.h for all heap.h users.

      [regexp][liveedit] Fix inconsistent JSArrays · bb9707c8
      jkummerow authored 
      The hand-written KeyedLoadIC_Megamorphic stub didn't care about JSArray
lengths, which made it lenient towards said lengths being wrong, but it
will soon fix that bug and thereby become more strict.

LiveEdit: factory->NewJSArray(capacity) doesn't set a length, so set it
manually.
RegExp: to avoid having to take care of array length updating in the
RegExpExecStub, just use a JSObject instead.
