      [turbofan] Properly optimize instanceof (even in the presence of @@hasInstance). · 241c024c
      bmeurer authored 
      This is the TurboFan counterpart of http://crrev.com/2504263004, but it
is a bit more involved, since in TurboFan we always inline the appropriate
call to the @@hasInstance handler, and by that we can optimize a lot more
patterns of instanceof than Crankshaft, and even yield fast instanceof
for custom @@hasInstance handlers (which we can now properly inline as
well).

Also we now properly optimize Function.prototype[@@hasInstance], even if
the right hand side of an instanceof doesn't have the Function.prototype
as its direct prototype.

For the baseline case, we still rely on the global protector cell, but
we can address that in a follow-up as well, and make it more robust in
general.

      [promises] Move CreateResolvingFunctions to c++ · cb6c8e48
      gsathya authored 
      - A new runtime function (%create_resolving_functions) is installed to
  call the CreateResolvingFunctions builtin from JS.

- Three new builtins are created - resolve and reject functions and a
  third function that creates a new JSFunctions from these
  resolve/reject builtins.

- The promise reject function is installed on the context temporarily
  as internal_promise_reject. This should go away once we remove
  PromiseSet.

      Simplify accesses to Script::line_ends · e730d088
      jgruber authored 
      line_ends is either undefined (if uninitialized) or a fixed array (after
Script::InitLineEnds). All accesses from JS have been removed, therefore
we can skip assigning a COW map and remove the accessor.

      [typedarrays] Remove duplicate initial map creation · 9e07c96f
      gsathya authored 
      Previously we created a duplicate map because we couldn't set the
correct ElementsKind when we created the function. This patch updates
the ElementsKind field of the existing map directly instead of
creating a new one.

This patch also correctly sets the instance_size when we create the
map the first time.

      [Tracing] Use TracingCategoryObserver in gc statistics · 7d28301d
      lpy authored 
      This patch is a follow-up patch to enable gc statistics to use
TracingCategoryObserver.

Previously we need to pass --track_gc_object_stats to v8 if we want to enable
gc statistics in tracing. In this patch, we introducce an integer flag
FLAG_gc_stats, and FLAG_track_gc_object_stats and FLAG_trace_gc_object_stats
will set it to 0x01, tracing will set it to 0x10 when we start tracing and
reset the bit when we stop tracing.
