48eff34c32 [es6] don't "replace" Object.prototype.toString for --harmony-tostring
When ObjectToString is installed on Object.prototype twice (once in v8natives.js, and once in harmony-tostring.js), this pollutes old code spaces on some devices. To prevent this, the function is only installed once, preventing test failures when the --harmony-tostring flag is flipped on by default.

a5d71c2cac PPC: JSEntryTrampoline: check for stack space before pushing arguments
Port 146598f44a

Original commit message:
Optimistically pushing a lot of arguments can run into the stack limit of the process, at least on operating systems where this limit is close to the limit that V8 sets for itself.

96ef78aa0b [turbofan] Fix FrameInspector when deoptimizer is disabled.
This is a workaround to make the debugger happy about TurboFan frames
when the debugger causes frame inspection. Note that this can happen
because the debugger can be activated while there still are optimized
TurboFan activations on the stack.

9b09a28d5c Remove comparison operator and helper function from AstRawString interface
These comparisons are only meant to be done by AstValueFactory itself (in
its string_table_ operations), so make the Compare() function a private
member of AstValueFactory.

All other clients of AstRawStrings should compare them by pointer value.
There were only two clients which failed to abide by this rule, one
recently-added (in ModuleDescriptor) and the other in Literal::Match
(in ast.cc, added in https://code.google.com/p/v8/source/detail?r=24396).

f190a6d23d [turbofan] Add poor man's store elimination for storing to fields.
This is a very simple dead store elimination that removes StoreField
nodes which are immediately followed by other StoreField nodes that
store to the same field. Ideally there should be a fully featured store
elimination, which walks over the effect graph starting from the end,
but there are some technical difficulties to solve before we can get to
that, esp. we need to think about "effect producing" operators like
ValueEffect first. Once we have that, it is trivial to remove this temporary
poor man's store elimination.

56600a35a4 X87: Reimplement Maps and Sets in JS
port 909500aa1d (r27605)

original commit message:
    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).

d995d4bd4b [TurboFan] Fixed handling of CompareIC return type.
Although all this code might be moved around later, it's a good idea
to unhackify it now. :-)

af293729ad Tests that carefully checks opt/deopt status shouldn't --always-opt.
If we optimize a function before gathering feedback it may be
peppered with soft deoptimizations. So it can't help but deoptimize.
A judicious reading of the code isn't enough to determine what the
optimization state should be in the face of such chaotic gyrations.
