b3422df4ca Re-land "Removed one copy-n-paste clone of HGraphBuilder::BuildStoreNamed." 
The previous CL used the wrong map in some cases, leading to a wrong decision
regarding monomorphic usage and therefore some performance regressions.

98db1a369d Implement proper module linking. 
Specifically:

- In parser, check that all exports are defined.
- Move JSModule allocation from parser to scope resolution.
- Move JSModule linking from full codegen to scope resolution.
- Implement module accessors for exported value members.
- Allocate module contexts statically along with JSModules
  (to allow static linking), but chain them when module literal is evaluated.
- Make module contexts' extension slot refer to resp. JSModule
  (makes modules' ScopeInfo accessible from context).
- Some other tweaks to context handling in general.
- Make any code containing module literals (and thus embedding
  static references to JSModules) non-cacheable.

This enables accessing module instance objects as expected.
Import declarations are a separate feature and do not work yet.

6139bafd28 Also in ClearNonLiveTransitions we have to check if there still is a transition array before we access it. 
This should never happen in the long run, but will happen when maps still have a back-pointer while the forward pointer (the transition) was overwritten.

d7a5b7d5e2 Separating transitions from descriptors. 
In this design maps contain descriptor arrays, which in turn can contain transition arrays. If transitions are needed when no descriptor array is present, a descriptor array without real descriptors is inserted just so it can point at the transition array.

The transition array does not contain details about the field it transitions to. In order to weed out transitions to FIELDs from CONSTANT_FUNCTION (what used to be MAP_TRANSITION vs CONSTANT_TRANSITION), the transition needs to be followed and the details need to be looked up in the target map. CALLBACKS transitions are still easy to recognize since the transition targets are stored as an AccessorPair containing the maps, rather than the maps directly.

Currently AccessorPairs containing a transition and an accessor are shared between the descriptor array and the transition array. This simplifies lookup since we only have to look in one of both arrays. This will change in subsequent revisions, when descriptor arrays will become shared between multiple maps, since transitions cannot be shared.
