a01b45df58 Fix a number of tests that incorrectly used assertUnreachable.
Our testing infrastructure uses exceptions to indicate
errors. assertUnreachable therefore throws an exception to indicate
that it was reached. Therefore, it cannot be used to check that an
exception was thrown using the pattern:

try {
  shouldThrow();
  assertUnreachable();
} catch(e) {
}

Such a test will always pass because assertUnreachable will throw an
exception if shouldThrow does not.

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.

9c89aa6dd9 Fix bugs 992 and 1083
Fixes JS portion of DefineOwnProperty when there is
an existing property and the new descriptor is generic.

Makes code follow spec steps more closely.

Fixes typo for check for unchanged enumerable in step 6.

Adds regression tests.
Fixes errors in object-define-property test

Don't normalize the JSGlobalProxy. Gets webkit http/tests/security/xss-DENIED-defineProperty.html working.

cd6bd8c4fa Revert 6220 (generic descriptor support in Object.defineOwnProperty)
This change caused a webkit failure in http/tests/security/xss-DENIED-defineProperty.html.

 I will look into this and reapply when I find a solution.

357afa385b Change Object.defineProperty to accept undefined as getters and setters and to correctly accept overriding an accessor with a data property.
In the past we only accepted functions as argument for setting an
accessor. Since one should be able to set an accessor to undefined
this had to be changed to take either.

In addition, we did not lookup properties in the prototype chain,
causing us to call the setter of an existing accessor up the prototype
chain when trying to replace an existing accessor (that was not local)
with a data property.

de512af068 Add support for elements and array indices in Object.defineProperty
(fixes bug 619).

This also fixes a bug in GetOwnProperty in runtime.cc discovered by
the new test cases. That part of the code was not testable before
since we had no way of correctly defining properties on elements.

95939ada29 Fix issue 720 making Object.defineProperty handle existing writable flags correctly.
The existing version will overwrite the existing writable flag with
false even in the case where no new value is given and the existing
writable flag is true.

The reason for the issue is that there is no check to see if the
provided descriptor actually has a writable attribute. This causes us
to use the default value (false) even in the case where nothing was
provided. In addition, the existing tests makes wrong assumptions (that writable is always set to false if not provided) and has been changed to follow the specification.

fb58bc06c6 Fixes issue 712 causing non-configurable accessors to be overwritable by using
Object.defineProperty with empty property descriptor.

The issue is fixed by implementing step 5 and 6 from DefineOwnProperty in the
specification (ES5 8.12.9).

This also fixes a bug in SameValue when used on boolean values (it
would priorly return a number - not a boolean).

a28143c77c Added extra tests to the DefineOrRedefineAccessorProperty and
DefineOrRedefineDataProperty to avoid invalid input.

Added tests to object-define-property.js to test that it does not crash 
on invalid input.

f74a08d8ee Added Object.defineProperty + needed internal functionality:
DefineOwnProperty (changed to allow for redefinition of existing property)
  SameValue
  Extra info on propertydescriptor
  GetProperty
  HasProperty

Currently the DefineOrRedefineAccessorProperty deletes the existing
property on the object if it is a dataproperty (FIELD or NORMAL) and
adds a new one. This can potentially be optimized.
