      Move builtin JavaScript sources into own directory. · e5320d8a
      mstarzinger authored 
      This moves JavaScript source files that are bundled with V8 into a
separate directory. The goal is to improve code readability and also
being able to formalize ideal reviewers by subsequently adding the
OWNERS file. These files almost exclusively contain implementations
of methods fully specified by ES6.

Note that files in the "debug" directory as well as the "d8.js" file
aren't affected by this change.

      [es6] Fix missing bits for full @@toPrimitive support. · 2a0759d3
      bmeurer authored 
      Introduce %_ToNumber intrinsic, which just calls to the existing
ToNumberStub, and remove all uses of our custom JavaScript plus
intrinsics based ToNumber and friends.

Also replace the TO_NUMBER_INLINE macro with TO_NUMBER,
which is currently a wrapper for %_ToNumber. Newly written JS
code should use TO_NUMBER (similar to TO_STRING, TO_INT32,
and friends).

Also finally remove the DefaultString/DefaultNumber builtins, which
are basically the ES5 version of ToPrimitive. Now all code uses the
ES6 version, which is implemented in Object::ToPrimitive and
JSReceiver::ToPrimitive in C++.

      [es6] Introduce %ToInteger and %ToLength. · 93b2b262
      bmeurer authored 
      This adds ES6 compliant Object::ToInteger, Object::ToInt32,
Object::ToUint32 and Object::ToLength, and replaces the old
Execution wrappers of those abstract operations (which were
not using the correct ToPrimitive).

This also introduces proper %ToInteger and %ToLength runtime
entries, with a fast path %_ToInteger supported in fullcodegen
and Crankshaft (for now). Internal JavaScript code should use
TO_INTEGER and TO_LENGTH respectively.

      [runtime] Replace %to_string_fun with %_ToString. · 7a7b692b
      bmeurer authored 
      Introduce a new macro TO_STRING that maps to %_ToString and use that
instead of calling into any of the ToString/NonStringToString JavaScript
builtins. Also remove the TO_STRING_INLINE macro, which is basically
obsolete with %_ToString. We still have a few uses of ToString left (via
the utils export mechanism), where we need to investigate whether we
will tank badly if we replace them with TO_STRING as well.

      ES6: Array.prototype.slice and friends should use ToLength instead of ToUint32 · d4e1299f
      aperez authored 
      Defines a new --harmony-tolength flag, and a ToLengthFlagged() runtime function,
that is used where ES6 requires ToLength(), but a pre-ES6 conversion existed
before. When the flag is disabled, the function uses TO_UINT32(), which is
the pre-ES6 behaviour. When the flag enabled, the ES6-compliant ToLength()
conversion is used.

Based on a patch initially from Diego Pino <dpino@igalia.com>

      [runtime] Replace many buggy uses of %_CallFunction with %_Call. · db2ba190
      bmeurer authored 
      The semantics of the %_CallFunction intrinsic seem to be very unclear,
which resulted in a lot of bugs. Especially the combination with
%IsSloppyModeFunction is always a bug, because the receiver would be
wrapped in the wrong context. So the %IsSloppyModeFunction helper is
gone now, and many of the buggy uses of %_CallFunction are also
eliminated.

If you ever need to call something with a different receiver, then
%_Call is your friend now. It does what you want and implements the
call sequence fully (and correct).

      [es6] Initial steps towards a correct implementation of IsCallable. · 8a378f46
      bmeurer authored 
      This turns the has_instance_call_handler bit on Map into an is_callable
bit, that matches the spec definition of IsCallable (i.e. instances have
[[Call]] internal methods).

Also fix the typeof operator to properly say "function" for everything
that is callable.

Also remove the (unused) premature %_GetPrototype optimization from
Crankshaft, which just complicated the Map bit swap.
