f135cfa263 X87: Move function prototype handling into a special handler rather than IC 
port r22526.

original commit message:
  Move function prototype handling into a special handler rather than IC

  Adjust hydrogen handling of function.prototype to be based on map feedback.
  Handle non-instance prototype loading using an IC rather than in the hydrogen
  instruction. In the future, remove the special instruction and replace by multiple
  hydrogen instructions.

port r22500.

original commit message:

  Introduce FLAG_vector_ics.

  When FLAG_vector_ics is true, then AST nodes that use Load and KeyedLoad ICs
  will allocate a type vector slot to store feedback information. Full codegen
  will emit a load of the slot into a register if the flag is on.

  Support is incomplete, right now the IC doesn't know how to use the feedback
  slot.

will allocate a type vector slot to store feedback information. Full codegen

de8cac4450 Make GCTracer persistent. 
This is essentially https://codereview.chromium.org/390823003/. It turns
out that it's safe to use a persistent GCTracer instead
of creating and destroying GCTracers for each GC, because
Scavenge and Mark-Sweep steps never overlap, and the tracking of
incremental marking also happens separately for the two types of GC.
Tracking of incremental marking will be moved into the GCTracer in a
follow-up patch.

54636ae4e2 StubCallInterfaceDescriptor and CallInterfaceDescriptor are unified under a base class InterfaceDescriptor. 
Handling of the context register had to be massaged to effect the unification. This will make it easier to call hydrogen code stubs directly from crankshaft.

was present before r22293 to resolve this.

1b5848c210 Some fixes to avoid breakages when enabling out-of-line constant pools. 
Three fixes which are required to pass all the tests when  out-of-line constant
pools are enabled for Arm:

 - Invalidate embedded objects in optimized code when it is deoptimized such
   that the weak pointers in the constant pool array are cleared.  This prevents
   a CHECK(heap_->mark_compact_collector()->IsMarked(object)) error when a
   verifying weak pointers in a deoptimized code object's constant pool.
 - Modify LargeObjectSpace::Verify to allow constant pool arrays in the
   large object space.
 - Increase the 32bit stack size limit, since the constant pool pointer
   is now on every stack frame, causing the size of each stack frame to
   increase by one word, and causing deep-recursion-test to fail.

a42612b4a7 Change ScriptCompiler::CompileOptions to allow for two 'cache' modes 
(parser or code) and to be explicit about cache consumption or production
(rather than making presence of cached_data imply one or the other.)

Also add a --cache flag to d8, to allow testing the functionality.

-----------------------------
API change

Reason: Currently, V8 supports a 'parser cache' for repeatedly executing the same script. We'd like to add a 2nd mode that would cache code, and would like to let the embedder decide which mode they chose (if any).

Note: Previously, the 'use cached data' property was implied by the presence of the cached data itself. (That is, kNoCompileOptions and source->cached_data != NULL.) That is no longer sufficient, since the presence of data is no longer sufficient to determine /which kind/ of data is present.

Changes from old behaviour:

- If you previously didn't use caching, nothing changes.
Example:
  v8::CompileUnbound(isolate, source, kNoCompileOptions);

- If you previously used caching, it worked like this:

  - 1st run:
  v8::CompileUnbound(isolate, source, kProduceToCache);
  Then, source->cached_data would contain the
  data-to-be cached. This remains the same, except you
  need to tell V8 which type of data you want.
  v8::CompileUnbound(isolate, source, kProduceParserCache);

  - 2nd run:
  v8::CompileUnbound(isolate, source, kNoCompileOptions);
  with source->cached_data set to the data you received in
  the first run. This will now ignore the cached data, and
  you need to explicitly tell V8 to use it:
  v8::CompileUnbound(isolate, source, kConsumeParserCache);

23887bf978 X87: Clean up and update const / var 
port r22379

original commit message:
This CL simplifies var / const by ensuring the behavior is consistent in itself,
and with regular JS semantics; between regular var/const and eval-ed var/const.

Legacy const is changed so that a declaration declares a configurable, but non-writable, slot,
 and the initializer reconfigures it (when possible) to non-configurable non-writable. This
 avoids the need for "the hole" as marker value in JSContextExtensionObjects and GlobalObjects.
Undefined is used instead.

319e5226e9 fix the vtune support bug. 
During https://code.google.com/p/v8/source/detail?r=19925 checkin context bound scripts (Script)
and context unbound scripts (UnboundScript) are Distinguished.

And then Sven Panne helped to fix the vtune support compilation
error in https://code.google.com/p/v8/source/detail?r=20955.

The problem is that there is runtime error for vtune
support.
In our original implementation, we encapsulated and passed v8::internal::Script
to V8 API. It will leads to type check error for current V8::Script definition.

So I changed the Handle<Script> definition in JitCodeEvent
to Handle<UnboundScript>
 and add the corresponding change in log.cc.

If you do NOT prefer to change in include/v8.h. I think I can change the definition of
CodeEventLogger::LogRecordedBuffer(...) so that the we can pass the correct
type (JSFunction) as V8::Script to V8 API.

70da8959bc Implement handling of arrow functions in the parser 
Arrow functions are parsed from ParseAssignmentExpression(). Handling the
parameter list is done by letting ParseConditionalExpression() parse a comma
separated list of identifiers, and it returns a tree of BinaryOperation nodes
with VariableProxy leaves, or a single VariableProxy if there is only one
parameter. When the arrow token "=>" is found, the VariableProxy nodes are
passed to ParseArrowFunctionLiteral(), which will then skip parsing the
paramaeter list. This avoids having to rewind when the arrow is found and
restart parsing the parameter list.

Note that the empty parameter list "()" is handled directly in
ParsePrimaryExpression(): after is has consumed the opening parenthesis,
if a closing parenthesis follows, then the only valid input is an arrow
function. In this case, ParsePrimaryExpression() directly calls
ParseArrowFunctionLiteral(), to avoid needing to return a sentinel value
to signal the empty parameter list. Because it will consume the body of
the arrow function, ParseAssignmentExpression() will not see the arrow
"=>" token as next, and return the already-parser expression.

The implementation is done in ParserBase, so it was needed to do some
additions to ParserBase, ParserTraits and PreParserTraits. Some of the
glue code can be removed later on when more more functionality is moved
to ParserBase.

Additionally, this adds a runtime flag "harmony_arrow_functions"
(disabled by default); enabling "harmony" will enable it as well.

e5991fc373 Implement handling of arrow functions in the parser 
Arrow functions are parsed from ParseAssignmentExpression(). Handling the
parameter list is done by letting ParseConditionalExpression() parse a comma
separated list of identifiers, and it returns a tree of BinaryOperation nodes
with VariableProxy leaves, or a single VariableProxy if there is only one
parameter. When the arrow token "=>" is found, the VariableProxy nodes are
passed to ParseArrowFunctionLiteral(), which will then skip parsing the
paramaeter list. This avoids having to rewind when the arrow is found and
restart parsing the parameter list.

Note that the empty parameter list "()" is handled directly in
ParsePrimaryExpression(): after is has consumed the opening parenthesis,
if a closing parenthesis follows, then the only valid input is an arrow
function. In this case, ParsePrimaryExpression() directly calls
ParseArrowFunctionLiteral(), to avoid needing to return a sentinel value
to signal the empty parameter list. Because it will consume the body of
the arrow function, ParseAssignmentExpression() will not see the arrow
"=>" token as next, and return the already-parser expression.

The implementation is done in ParserBase, so it was needed to do some
additions to ParserBase, ParserTraits and PreParserTraits. Some of the
glue code can be removed later on when more more functionality is moved
to ParserBase.

Additionally, this adds a runtime flag "harmony_arrow_functions"
(disabled by default); enabling "harmony" will enable it as well.

2) BufferedUtf16CharacterStream::FillBuffer doesn't need the length
argument. The length is always kBufferSize and the subclasses can just read it

ae6496e6ea [Arm]: Optimize ConstantPoolBuilder::Populate code by minimizing calls to OffsetOfElementAt 
Calling OffsetOfElementAt becomes expensive when compiling functions with many
constant pool entries.  This was causing a regression in MandreelLatency due
to the time spent populating the constant pool array for large compiled
functions.

This change avoids calling OffsetOfElementAt for each entry, and instead keeps
track of the current offsets in ConstantPoolBuilder::Populate.  This gives the
following improvements on a Nexus 5:

                     Inline CP  |  OOL CP (before CL)  |  OOL CP (after CL)
Mandreel:               4305    |        3961          |       4120
MandreelLatency:        2298    |        1198          |       1994
Octane Score:           5197    |        4982          |       5152
