6bd8d27a65 MIPS: Fixed a bug in StringHelper::GenerateTwoCharacterSymbolTableProbe. 
r9871 (5baeaf57) changed the fill value for deleted entries in hash tables from null_value to the_hole_value.
This commit changes an assertion in MIPS code that expects this value.

b8dc77ab9a Fix Heap::Shrink to ensure that it does not free pages that are still in use. 
Heap::Shrink is called from EnsureFromSpaceIsCommitted at the very start of the GC. At this moment live bytes counts on pages are in inconsistent states. Some pages might have been already swept but have not been yet reached by an incremental marker (or incremental marker is not in progress) and have live bytes count set to 0. Thus we can't rely only on LiveBytes to determine which pages can be released to the OS.

33682c6b34 Implement inline runtime function %_SetValueOf for Crankshaft. 
It is frequently used inside our builtins and is implemented purely
by HIR instructions: a smi check, an instance-type check and an
in-object property store for storing to the value field.

  the bools are packed.
* Rename SaveScope and LexicalScope in the parser.
* Use an enum to generate the numbers 0..N and the dependent count, rather
  than static const ints.  This is simpler to extend (coming in a future

b16e02e823 Made PropertyType handling even more explicit. 
Replaced FIRST_PHANTOM_PROPERTY_TYPE by a predicate. Removed the (hopefully)
last default cases for switches on PropertyType. Benchmarks show that both
changes are performace-neutral.

Now every value of PropertyType should either be handled by an explicit case in
a switch or by an equality operator. Therefore, the C++ compiler should finally
be able to tell us which places to touch when changing PropertyType.

49df2a6ddc A page created a number of ConsStrings that refer to one big string. 
Each such string requires small amount of heap memory.
Heap snapshot generator copies all the strings into internal hash map for future use.
The each copy requires much more memory than original v8 string.

I made a workaround for this. The snapshot will copy only first 1024 symbols.
A simple drive-by fix was made for a performance problem in ToCString implementation.

e24c612a5e Fix setting array length to be ES5 conform. 
This also refactors the way we set the length of an arrays' backing
store to use the new elements accessor interface. The actual fix is in
DictionaryElementsAccessor::SetLengthWithoutNormalize() where we first
search for non-deletable elements according to ES5 section 15.4.5.2
specifications.

Snippet from the specification: Attempting to set the length property of
an Array object to a value that is numerically less than or equal to the
largest numeric property name of an existing array indexed non-deletable
property of the array will result in the length being set to a numeric
value that is one greater than that largest numeric property name.

2a1f08a1c2 Improve dominator computation to avoid worst-case quadratic time. 
In case of a degenerated CFG like in the example below processing
predecessors in the wrong order yields n^2 runtime.

  do {
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    if (x) break;
    // etc.
  } while (false);

Reversing iteration order avoids this.

36b715b1bd Refactoring only: Make the handling of PropertyType more explicit. 
Do not rely on 'default' clauses or 'if's when analysing a PropertyType, because
this makes it hard to find the relevant places when a new type is added. Note
that the detection of "phantom property types" is left untouched, because this
might have a performance impact, especially for the GC (to be investigated).

This is a preliminary step for introducing a new kind of map transition.

ea18539244 Tune context allocation for variables accessed from inner scopes. 
After introduction of with scopes we have enough static information to omit
context allocation in the case that a variable is accessed from a nested block
or catch scope of the same function. Only variables accessed from the inside of
a nested function or with scope are forced to be allocated in the context.

This essentially reverts

d00b82ff91 MIPS: updated atomic operations. 
Specifically:
-fixed a bug in CompareAndSwap that caused randomly occuring timeouts on MIPS boards.
-added gcc inline asm control push/pop instructions to correctly save/restore the reorder setting instead of simply assuming it should be enabled.
-reordered/optimized some instructions to utilize MIPS-specific pipelining features (branch delay slot).
-fixed improper usage of write barriers

ee3197d309 MIPS: Handlify CompileConstructStub and the remaining CallStubCompiler functions. 
Port r9837 (38061af).
Port r9834 (95ac04).

Original commit message (r9834):
Also, handlify functions for loading with interceptors and callbacks.
Remove some unneeded code.  Rename Foreign::address() because it
confusingly shadows HeapObject::address() which does something quite
different.

e05c04e5fa Handlify CallStubCompiler::CompileCallField. 
This function relies on a number of helpers for checking prototypes and
probing dictionaries.  It is not possible to wrap these helpers to retry
after allocation failure in a safe way---the assembler has no way to undo
what it has already assembled.

These functions have all been duplicated with handle and raw versions.  The
raw versions will eventually be removed completely.

e8bccc2cb0 Block scoped const variables. 
This implements block scoped 'const' declared variables in harmony mode. They
have a temporal dead zone semantics similar to 'let' bindings, i.e. accessing
uninitialized 'const' bindings in throws a ReferenceError.

As for 'let' bindings, the semantics of 'const' bindings in global scope is not
correctly implemented yet. Furthermore assignments to 'const's are silently
ignored. Another CL will introduce treatment of those assignments as early
errors.

This change is based on my previous change enabling inlining calls-as-function
fixing the bugs related to deoptimization.

The function value on top of the environment was dropped too late in the old code.
As a result we could get a wrong value on top after deoptimization.

This change includes r9619. It was reverted because of test failures that are fixed
with this patch.

3edfb4bbbc Make IsGenericDescriptor spec-conformant. 
When the descriptor argument is undefined, the spec is very explicit about the
fact that we should return false (not true, like we did previously). I couldn't
come up with a test case for this, but the old code leaves a bad feeling about
corner cases, so better play safe.

6742176949 Fix Array.filter to use internal array for result. 
In built-in code we use arrays for internal computations. This makes it
possible to affect the built-in code by putting getters or setters on
the array prototype chain. Using internal arrays prevents those issues.

aaf3454248 [[DefineOwnProperty]] should always return true/false (or throw an exception), never undefined. 
Note that this is not an observable behavior, but following the principle of
least surprise, we should follow the spec. Additional (extremely tiny) bonus:
Some ICs see fewer values => better code.
