      [debugger] tuned StepNext and StepOut at return position · e27d18c9
      kozyatinskiy authored 
      Proposed behaviour:
- StepNext at return position go into next function call (no changes with current behavior, but implemented in v8::Debug instead of hack on inspector side);
- StepOut at return position go into next non-current function call.

We need this to have better stepping in cases with native functions, blackboxed functions and/or different embedder calls (e.g. event listeners).

New behavior could be illustrated with two examples (for more see stepping-with-natives-and-frameworks test):
- let's assume that we've blackboxed callAll function, this function just takes its arguments and call one after another:
var foo = () => 1;
callAll(foo, foo, () => 2);
If we break inside of first call of function foo. Then on..
..StepNext - we're able to reach second call of function foo,
..StepOut - we're able to reach () => 2 call.

- let's consider case with native function:
[1,2,3].map(x => x * 2)
If we break inside of first callback call, then with StepNext we can iterate through all calls of callback, with StepOut we go to next statement after .map call.

Implementation details:
- when we request break we schedule step-in function call for any step action at return position and for step-in at any position,
- when we request StepOut at return position - we mark current function as needed-to-be-ignored inside of PrepareStepIn(function) call,
- when we request StepOut at not return position - we set break at return position and ask debugger to just repeat last step action on next stepping-related break.

      Add templatized GlobalHandles::Create method · 857ec798
      Clemens Hammacher authored 
      The old method always returned a Handle<Object>, requiring an explicit
cast in the caller. This CL makes it return Handle<T> if called with a
T* as parameter.

Also, remove now redundant casts from callers.

      [rename] Rename internal field to embedder field. · 72e53936
      titzer authored 
      This CL renames all occurrences of "internal field" to "embedder field"
to prevent confusion. As it turns out, these fields are not internal to
V8, but are actually embedder provided fields that should not be mucked
with by the internal implementation of V8.

Note that WASM does use these fields, and it should not.

      Disentangle assembler from isolate. · 94b088ca
      neis authored 
      This is a first step towards moving Turbofan code generation off the main thread.

Summary of the changes:
- AssemblerBase no longer has a pointer to the isolate. Instead, its
  constructor receives the few things that it needs from the isolate (on most
  architectures this is just the serializer_enabled flag).
- RelocInfo no longer has a pointer to the isolate. Instead, the functions
  that need it take it as an argument.  (There are currently still a few that
  implicitly access the isolate through a HeapObject.)
- The MacroAssembler now explicitly holds a pointer to the isolate (before, it
  used to get it from the Assembler).
- The jit_cookie also moved from AssemblerBase to the MacroAssemblers, since
  it's not used at all in the Assemblers.
- A few architectures implemented parts of the Assembler with the help
  of a Codepatcher that is based on MacroAssembler.  Since the Assembler no
  longer has the isolate, but the MacroAssembler still needs it, this doesn't
  work anymore.  Instead, these Assemblers now use a new PatchingAssembler.

These changes were reverted to improve a perf regression on a Chrome
bot. Since then, the regression has reappeared, then disappeared again
all from seemingly unrelated changes.

      [inspector] don't make v8::debug::Call for breakProgram. · c418902b
      kozyatinskiy authored 
      We emulate break by callling breakProgramCallback function in debugger context, we can just use HandleDebugBreak.
It allows us to move all stepping logic to debug.cc later and remove one usage of debugger context.
+ two minor issues fixed, see tests.

      [builtins] (Re-)implement Array.prototype.every/some with the CSA · 6e0496b2
      danno authored 
      In the process, re-factor the implementation of Array.prototype.forEach so that
the bulk of the implementation can be re-used, since much of the spec is
identical. The refactor should also make it more straight-forward to implement
map and filter. The re-factored version only have a single slow path for processing
elements which is used for both the overall slow path and for the bailout from the
FAST_ELEMENTS case.
