      [Ignition] Use binary operation feedback from Ignition to Crankshaft. · 245e5b32
      mythria authored 
      Ignition collects type feedback for binary and compare operations in type
feedback vector and FCG uses Binary/CompareOpICs to collect type feedback.
The feedback collected by ignition is not used by crankshaft. This hits the
performance, when trying to optimize functions that did not tier upto FCG.
This cl merges the feedback collected by ignition and FCG when passing to
crankshaft.

      Forking the type system between Crankshaft & Turbofan. · 17e9e2f4
      mvstanton authored 
      Our Type class has a semantic and representational dimension.
Much code in src/ast, Crankshaft and Turbofan is based on it.
Going forward in Turbofan we'd like to remove representational information
entirely. To that end, new type AstType has been created to preserve
existing behavior for the benefit of Crankshaft and the AST.

      [stubs] Introduce a proper ToBooleanStub. · d1df58e8
      bmeurer authored 
      Rename the existing (patching) ToBooleanStub to ToBooleanICStub to match
our naming convention, and add a new TurboFan-powered ToBooleanStub,
which just does the ToBoolean conversion without any runtime call or
code patching, so we can use it for Ignition (and TurboFan).

Drive-by-fix: Add an Oddball::to_boolean field similar to the ones we
already have for to_string and to_number, so we don't need to actually
dispatch on the concrete Oddball at all.

      Vector ICs: The Oracle needs to report feedback for the object literals and the count operation. · 752b0308
      mvstanton authored 
      The refactoring is because it's awkward and error-prone to deterimine which IC slot an
ObjectLiteralProperty uses for feedback. The fix is for each one to know it's own slot. In the
numbering pass, we allocate slots for the ObjectLiteral, then hand out those slots into the
properties.

It adds one word to the ObjectLiteralProperty expression - I'm investigating if thats a
problem.

This changes makes compiling the object literal cleaner across the three compilers. Also, the
slot allocation logic in ObjectLiteral::ComputeFeedbackRequirements() was refactoring to mimic
the style in full-codegen. This is useful since it must remain in sync with
FullCodegen::VisitObjectLiteral().

      Remove the dependency of Zone on Isolate · c7b09aac
      danno authored 
      Along the way:
- Thread isolate parameter explicitly through code that used to
  rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
  affected code
- Change Hydrogen New<> instruction templates to automatically
  pass isolate
