eb14637367 CpuProfiler: eliminate 2 layers of 4 for CodeCreateEvent calls. 
The bodies of methods in ProfilerEventProcessor were moved into CpuProfiler.
Multiple NewCodeEntry methods in CpuProfilesCollection were replaced with one which
simply passes arguments to the CodeEntry constructor.
And CpuProfiler just calls this method when it needs a CodeEntry object.

This NewCodeEntry method is required because CpuProfilesCollection keeps ownership of CodeEntry objects.

daf4101aa4 Fix infinite loop in regress-opt-after-deopt. 
%CompleteOptimization attempts to install optimized functions
that the parallel thread has put on the output queue, as long as
the function is marked with a builtin.  However, activating the
debugger will set all functions to the lazy recompile builtin,
without the function being on the parallel recompilation pipeline.
So we wait for the function to finish parallel recompilation
while it's marked by a builtin that's unrelated to parallel
recompilation.

75451d3c2c Add dependency to ICU 4.6 
We use the patched version from the chromium project, as it already has
a gyp file and allows for using the system icu instead of the bundled
version if desired.

081a9d1791 MIPS: Hydrogen array constructor cleanup and improvements. 
Port r15383 (3e90aaf)

Original commit message:
* Cleanup of LCallNewArray::PrintDataTo() method
* Created HCallNewArray::PrintDataTo()
* Created many more tests in array-constructor-feedback.js
* Removed redundant instructions in
GenerateRecordCallTarget
* Bugfix in CreateArrayDispatchOneArgument: on a call to
new Array(0), we'd like to set the type feedback cell to
a packed elements kind, but we shouldn't do it if the
cell contains the megamorphic sentinel.
* When used from crankshaft, ArrayConstructorStubs can
avoid verifying that the function being called is the
array function from the current native context, relying
instead on the fact that crankshaft issues an
HCheckFunction to protect the constructor call. (this
new minor key is used in LCodeGen::DoCallNewArray(), and
influences code generation in
CodeStubGraphBuilderBase::BuildArrayConstructor()).
* Optimization: the array constructor specialized for
FAST_SMI_ELEMENTS can save some instructions by looking
up the correct map on the passed in constructor, rather
than indexing into the array of cached maps per element
kind.

ae8fee5aca Roll gyp to r1656 
r1656 contains a bug fix for the make generator to correctly regenerate
Makefiles if a gyp was touched. Before, it would assume that it is
running in the top-level directory. However, the v8 standalone build
puts the generated Makefile into the out subdirectory, and so gyp
failed to locate the gyp binary.

The check for internalized strings relied on the fact that we had less

check needs to be more comprehensive. In fact, two bits need to be

Close a small gc window that exists between when a HNewArrayCall instruction is
created and the ElementsKind type feedback for the construction function is
accesses.

6aed526733 The check for internalized strings relied on the fact that we had less 
than 64 distinct InstanceTypes. We are hitting that boundary, so this
check needs to be more comprehensive. In fact, two bits need to be
tested: verify that kNotStringTag isn't set, and that kInternalizedTag
is set.

2f81a79d5a Refactor Hydrogen environment liveness analysis into an HPhase. 
Rename EnvironmentSlotLivenessAnalyzer to HEnvironmentLivenessAnalysisPhase,
following naming scheme suggested by danno@chromium.org in
https://codereview.chromium.org/17458002

The environment slot liveness analysis now uses the phase zone for
all its allocations.

dce010395d Turn zone_excess_limit_ into a constant. 
The zone_excess_limit_ is not changed at runtime, and there seems to
be no obvious reason to do so in the future.

073b1d1dfb Move phase_zone from CompilationInfo to CompilationPhase. 
Each CompilationPhase has its own zone, used for phase local
allocations. The zone of CompilationInfo should only be used
for non phase local allocations.
