      Rearranged intrinsic declarations according to their implementations. · cfe76e82
      svenpanne authored 
      Now every FOR_EACH_INTRINSIC_FOO sub-macro corresponds to a
src/runtime/runtime-FOO.cc file, even the order of runtime functions
within that file has been preserved in the corresponding macro, thanks
to some eye-hurting for/clang/sed/grep madness. ;-)

      Reimplement Maps and Sets in JS · 909500aa
      adamk authored 
      Previously, the only optimized code path for Maps and Sets was for String keys.
This was achieved through an implementation of various complex operations
in Hydrogen. This approach was neither scalable nor forward-compatible.

This patch adds the necessary intrinsics to implement Maps and Sets almost entirely
in JS. The added intrinsics are:

  %_FixedArrayGet
  %_FixedArraySet
  %_TheHole
  %_JSCollectionGetTable
  %_StringGetRawHashField

With these additions, as well as a few changes to what's exposed as runtime functions,
most of the C++ code backing Maps and Sets is gone (including both runtime code in
objects.cc and Crankshaft in hydrogen.cc).

      [es6] Throw TypeError for computed static prototype property name · 8d946b9c
      arv authored 
      The prototype of a class constructor function is read only. When we set
computed property names we were ignoring this and we were overriding the
property.

Since the prototype is the only possible own read only property on the
constructor function object we special case this so we do not have to
check this for every property in the class literal.

      [turbofan] Unify Math.floor / Math.ceil optimization. · 022ea7e0
      bmeurer authored 
      Provide an intrinsic %MathFloor / %_MathFloor that is used to optimize
both Math.ceil and Math.floor, and use the JS inlining mechanism to
inline Math.ceil into TurboFan code. Although we need to touch code
outside of TurboFan to make this work, this does not affect the way we
handle Math.ceil and/or Math.floor in CrankShaft, because for CrankShaft
the old-style builtin function id based inlining still kicks in first.

Once this solution is stabilized, we can use it for Math.floor as well.
And once that is settled, we can establish it as the unified way to
inline builtins, and get rid of the specialized builtin function id
based inlining at some point.

Note that "builtin" applies to basically every piece of internal
JavaScript/intrinsics based code, so this also applies to the yet to be
defined JavaScript based code stubs and handlers.
