9f04d73350 Make Error.prototype.name writable again, as required by the spec and the web. 
Address http://code.google.com/p/chromium/issues/detail?id=69187 by instead
ignoring getters on ReferenceError.prototype.name in Error.prototype.toString.

And while we're at it, do the same for SyntaxError and TypeError, and the
properties "message", "type", and "arguments" on all of them, which
potentially have similar issues.

065cc14449 Use map transitions when defining accessor properties. 
AccessorPairs can now contain map transitions, which is similar to our current
handling of CONSTANT_FUNCTION/CONSTANT_TRANSITION, but generalized to a pair for
holding info about the getter and the setter. This way we can achieve map
sharing for objects with accessor properties, which is a prerequisite for making
them fast via inlining. We fall back to the previous way of handling accessor
properties when sharing is not possible or we don't handle a special case.

Note: When an exisiting accessor property is redefined we could in principle
move the AccessorPair out of the descriptor into the object itself (again just
like the way we do something similar for CONSTANT_FUNCTION/CONSTANT_TRANSITION),
but this would require a new property kind for holding a pair of values. Perhaps
we can implement this later, but for now this hopefully rare case is handled
like before, losing map sharing and potentially creating more maps than strictly
necessary.

baf7ebd6da Fix assert triggered in fast/regex/pcre-test-4.html We were not filtering out 
all the nodes that had non-ASCII characters.  That has been fixed, but because
of the protection against over-deep recursion when filtering it is wrong to
assert that all nodes were filtered.  This change therefore also makes sure we
can cope with non-filtered nodes by adding back some code removed in

93113da5a2 Eliminate redundant array bound checks (checks already performed earlier in the DT). 
As a special case, for checks on index expressions with the form (expr + constant) if a smaller constant is checked later in the DT also eliminate the check.
Finally, if a larger constant is checked later in the same BB do the more general check (larger constant) earlier instead of the less general one.
This will not cause useless deoptimizations because, since we are in the same BB, all the checks would have been executed anyway.

ab26fb6b21 Implement rudimentary module linking. 
Constructs the (generally cyclic) graph of module instance objects
and populates their exports. Any exports other than nested modules
are currently set to 'undefined' (but already present as properties).

Details:
- Added new type JSModule for instance objects: a JSObject carrying a context.
- Statically allocate instance objects for all module literals (in parser 8-}).
- Extend interfaces to record and unify concrete instance objects,
  and to support iteration over members.
- Introduce new runtime function for pushing module contexts.
- Generate code for allocating, initializing, and setting module contexts,
  and for populating instance objects from module literals.
  Currently, all non-module exports are still initialized with 'undefined'.
- Module aliases are resolved statically, so no special code is required.
- Make sure that code containing module constructs is never optimized
  (macrofy AST node construction flag setting while we're at it).
- Add test case checking linkage.

62945585fd Implement ES5 erratum: global declarations shadow inherited properties. 
I also discovered that our treatment of const declarations is inconsistent
when inside a global eval under 'with' (i.e., when created by
DeclareContextSlots). That is,

  var x;
  eval("const x = 9")

and

  var x;
  eval("with({}) const x = 9")

differ (the former assigns 9, the latter throws). This appears to be an
oversight from earlier changes to our const semantics (the latter shouldn't
throw either). Fixing this is a separate issue, though (and one that doesn't
seem quite worthwhile).

7b59b1d5ac Fix array boilerplate object transitioning. 
Array literal boilerplate objects can be transitioned while existing
un-transitioned clones are still being populated. This adds a check that
prevents us from performing the same transition twice.

5798bc27aa Fix hidden properties to ignore [[Extensible]]. 
The [[Extensible]] property prevented the very first hidden property
from being added. If any hidden property was added to the object before
preventing extension, adding subsequent hidden properties would have
succeed however.
