6f775f2fb0 Fix calls of strict mode function with an implicit receiver. 
Only IA32 version for now. I'll start porting.

Strict mode functions are to get 'undefined' as the receiver when
called with an implicit receiver. Modes are bad! It forces us to have
checks on all function calls.

This change attempts to limit the cost by passing information about
whether or not a call is with an implicit or explicit receiver in ecx
as part of the calling convention. The cost is setting ecx on all
calls and checking ecx on entry to strict mode functions.

Implicit/explicit receiver state has to be maintained by ICs. Various
stubs have to not clobber ecx or save and restore it.

CallFunction stub needs to check if the receiver is implicit when it
doesn't know from the context.

7aec228dbb Cleanup of mjsunit.js code and make assertEquals more strict. 
Encapsulate the helper functions in mjsunit.js.
Now only exposes the exception class and the assertXXX functions.

Make assertEquals use === instead of ==.
This prevents a lot of possiblefalse positives in tests, and avoids
having to do assertTrue(expected === actual) when you need it.

Fixed some tests that were either buggy or assuming == test.

dab8f48ebc ARM: Implement correct rounding in the lithium codegenerator. 
This patch provides testing for values that have a fraction part of 0.5 and uses a different rounding method for them. The original method of VFPTruncating the value with round-to-nearest is not correct because it does not round to the larger number in case of a tie.

fa9e57e326 Change __defineGetter__ and __defineSetter__ to respect non-configurable. 
This makes us compatible with firefox. Earlier on we were somehow
compatible with safari - which will allow defining a getter even when
an existing getter is present and non-configurable. We would, however,
in addition to overwriting the getter also change configurable to
true. The approach used by firefox seems much more sound, i.e., why
should it be possible to use __defineGetter__ or __defineSetter__ to
overwrite a non-configurable getter or setter respectively.

I will file a bug on the webkit bugtracker.

56788625b6 Fix CPU profiling for Crankshaft. 
The main issue was due to multiple recompilations of functions.  Now
code objects are grouped by function using SFI object address.
JSFunction objects are no longer tracked, instead we track SFI object
moves. To pick a correct code version, we now sample return addresses
instead of JSFunction addresses.

tools/{linux|mac|windows}-tickprocessor scripts differentiate
between code optimization states for the same function
(using * and ~ prefixes introduced earlier).

DevTools CPU profiler treats all variants of function code as
a single function.

ll_prof treats each optimized variant as a separate entry, because
it can disassemble each one of them.

tickprocessor.py not updated -- it is deprecated and will be removed.

The old version only added extra space when we did indirect calls, but
the problem remains the same with normal calls that can be represented
as a single byte. When doing patching each call will always be at
least 2 bytes long because we use RUNTIME_ENTY as the reloc mode.

82cdd48b2f Fix a bug in deoptimization after logical expressions in an effect context. 
When deoptimizing to after an expression of the form (expr0 || expr1)
or (expr0 && expr1) in an effect context, the unoptimized code could
incorrectly see the value of the expression.

Handle the short-circuit binary operators specially in effect contexts.
This fixes the issue and will generate better code when the left
subexpression is boolean-valued.

The current version uses SetObjectProperty which will not set the
value in case this is a readonly property. The spec explictly says
that a configurable but non writable property can have its value
changed with Object.defineProperty (because the same thing can be
accomplished by doing 3 calls (set writable to true, update the value,
set writable to false).

check without first performing a heap object check.

Ensure that we do not get in JS code with a non-JSObject this value by
deoptimizing at Function.prototype.apply if the first argument is not a
JSObject.

48fadffcc4 Fix bug in JSON.parse for objects containing "__proto__" as key. 
It added the __proto__ key as a normal key, which made it visible
in enumeration, while reading still hit the hard-coded accessor.

c894b1f317 Fix bugs 992, 1083 and 1092 
My previous patch added an assert which uncovered 1092 in the sputnik tests.
This patch adds the fix for 1092, which is to ensure that NormalizeProperties
does not get called for a JSGlobalProxy along all code paths.

Add sputnik tests to .gitignore.

a2aa84873e Add regression test for the deoptimizer immediately followed by gc bug. 
In addition to the regression test I changed the gc-extension to take
a boolean flag specifying if compaction should be used (default is
false, existing tests will not change behaviour)

The regression test is disabled on arm and x64 with crankshaft
enabled. I made a bug to track this:

The arguments property of functions, if we find an optimized frame for
the function, is always a freshly allocated object.  We never try to
find an existing arguments object.

f1149734fc Partial fix for V8 issue 1079. 
Record a safepoint with a deoptimization id for throw in optimized code.  We
don't seem to much care what the AST ID is because we will not be using it
for lazy deoptimization (throw doesn't return to the point of throw).  For
hygiene we use the actual ID of the throw expression.  Throw is no longer a
control-flow instruction, but it's followed by an unconditional abnormal
exit.  This is required to insert a simulate between the throw and the exit.

Make our optimized treatment of Function.prototype.apply act like a call and
have side effects.  This ensures that it will get a lazy deoptimization
environment.  Use that deoptimization ID in the safepoint for the call.

Deleting a property was also missing a deoptimization ID, though there was a
deoptimization environment assigned to the instruction.  Record the
environment and use the deoptimization ID at the safepoint.

other situations.

Do not use overwritten Object.prototype.hasOwnProperty and
Array.prototype.pop. Do not use split and join in the error formatting
implementation. They are too big to control and their generality is
not needed.

4e7ddab6dc Fix a bug in the placement of minus-zero checks and in GVN. 
1. The placement of checks for negative zero has to be computed after
all conversion instructions have been inserted. I separated the code
into its own phase.

2. GVN need to take instruction flags into account when comparing
instructions for redundancy.
