The only difference to revision 7763 is the implementation in the
builtins file for arm and x64, plus a move of Array.prototype.toString
and Array.prototype.toLocaleString from should throw on null or
undefined to the non generic test cases in the function-call test (due
to us not currently supporting generic cases with these to functions)

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.

Fix %NewObjectFromBound to correctly handle optimized frames (including those with inlined functions).
Fix %_IsConstructCall handling in hydrogen: when called from inlined function return false constant directly instead of emiting HIsConstructCall.
Fix success case in TraceInline.

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.

Used incorrect register for referencing RegExp data, so it always failed
to match the fast case.
When modifiying the object layout, it was possible to make it crash instead.

When deoptimizing from the key subexpression of a keyed arguments access,
the unoptimized code expects to find the value of the receiver on the
expression stack. The environment of the optimizing compiler did not
contain this value during evaluation of the key subexpression.

Resubmit of patch for issue 1145 with a few additions:
- Now also clears exceptions when calling Runtime_LazyRecompile.
- Sets function where parsing fails to not be optimizable.

We can wrongly assume that exception which is not intended to be caught
by external try/catch should be caught if this exception inherits
external catcher from some previous exception. To prevent that,
clear external catcher when processing exceptions which cannot be
externally caught.

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.

Call accessors in the global object prototype when initializing global
variables. Function declarations are special cased for compatibility
with Safari and setters are not called for them. If this special
casing was not done webkit layout tests would fail.
Make the declaration of global const variables in the presence of
callbacks a redeclaration error.
Handle const context slot declarations conflicting with a CALLBACK as
a redeclaration error. That is, unless it is on a context extension
object which is not a real object and therefore conceptually have no
accessors in prototype chains. Accessors in prototype chains of
context extension objects are explicitly ignored in SetProperty.

The baseline compiler does not materialize a value for expressions of
the form !expr in an effect context so the graph translation should
not produce such an environment, otherwise we risk targeting it by
deoptimization.

We currently leave the exception as pending without returning a Failure::Exception() value. This is either caught immediately if running with --debug-code, or caught later by an assert in debug mode.
This change makes the pending exception be cleared before returning from the failed optimization attempt.

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.
