f15f294127 Sync laziness between BuildFunctionInfo and MakeFunctionInfo. 
BuildFunctionInfo compiles the function eagerly when there are debug
break points. However, the AST may have been parsed lazily since
MakeFunctionInfo does not check for debug break points.

This fixes a regression introduced in r11866.

0aacbf9619 Added %FlattenString and use it to speed up a regression test. 
Flattening strings is relatively costly and by doing it after every duplication
we avoid combinatorial explosion.

Note that flattening could have been done by e.g. using a regular expression,
too, but this is just another implementation detail and %FlattenString seems
general enough to be useful in other tests, too.

529f801fde Adapt Danno's Track Allocation Info idea to fast literals. When allocating a literal array, 
we store an AllocationSiteInfo object right after the JSArray, with a pointer to the
boilerplate object. Later, if the array transitions we check for the continued existence
of the temporary AllocationSiteInfo object (has no roots). If found, we'll use it to
transition the boilerplate array as well.

object with a length property. Accessing the property can cause an

76375de29d Object.observe: prevent observed objects from using fast elements. 
This is necessary because polymorphic stores generally
do not perform a map check but only an instance type check,
which misses out on changes in the observation status.
Unfortunately, there currently is no efficient way in V8
to maintain that optimisation in the presence of Object.observe.

6b16d0bcae Make Object.observe on the global object functional 
The approach in this change is to handle the unwrapping/wrapping of the global object transparently with respect to the JS implementation of Object.observe. An alternate approach would be to add a runtime method like %IsJSGlobalProxy and %UnwrapJSGlobalProxy, but it seems ugly to give JS (even implementation JS) access to the unwrapped global.

ce05280bfc Get rid of static module allocation, do it in code. 
Modules now have their own local scope, represented by their own context.
Module instance objects have an accessor for every export that forwards
access to the respective slot from the module's context. (Exports that are
modules themselves, however, are simple data properties.)

All modules have a _hosting_ scope/context, which (currently) is the
(innermost) enclosing global scope. To deal with recursion, nested modules
are hosted by the same scope as global ones.

For every (global or nested) module literal, the hosting context has an
internal slot that points directly to the respective module context. This
enables quick access to (statically resolved) module members by 2-dimensional
access through the hosting context. For example,

  module A {
    let x;
    module B { let y; }
  }
  module C { let z; }

allocates contexts as follows:

[header| .A | .B | .C | A | C ]  (global)
          |    |    |
          |    |    +-- [header| z ]  (module)
          |    |
          |    +------- [header| y ]  (module)
          |
          +------------ [header| x | B ]  (module)

Here, .A, .B, .C are the internal slots pointing to the hosted module
contexts, whereas A, B, C hold the actual instance objects (note that every
module context also points to the respective instance object through its
extension slot in the header).

To deal with arbitrary recursion and aliases between modules,
they are created and initialized in several stages. Each stage applies to
all modules in the hosting global scope, including nested ones.

1. Allocate: for each module _literal_, allocate the module contexts and
   respective instance object and wire them up. This happens in the
   PushModuleContext runtime function, as generated by AllocateModules
   (invoked by VisitDeclarations in the hosting scope).

2. Bind: for each module _declaration_ (i.e. literals as well as aliases),
   assign the respective instance object to respective local variables. This
   happens in VisitModuleDeclaration, and uses the instance objects created
   in the previous stage.
   For each module _literal_, this phase also constructs a module descriptor
   for the next stage. This happens in VisitModuleLiteral.

3. Populate: invoke the DeclareModules runtime function to populate each
   _instance_ object with accessors for it exports. This is generated by
   DeclareModules (invoked by VisitDeclarations in the hosting scope again),
   and uses the descriptors generated in the previous stage.

4. Initialize: execute the module bodies (and other code) in sequence. This
   happens by the separate statements generated for module bodies. To reenter
   the module scopes properly, the parser inserted ModuleStatements.

5e7b796479 Object.observe: Move notification of JSArray length changes to JSArray::SetElementsLength 
The previous implementation in Accessors::ArraySetLength failed when array length was set through StoreIC_ArrayLength. But that stub and the accessor both delegate to JSArray::SetElementsLength, so moving the code there allows notifications to be sent in both cases.

This fixes a corner case when the instance prototype of a function is
changed while inobject slack tracking is still in progress. This caused
the intial map to be unrelated for functions with the same shared info
and hence the shared construct stub is no longer generic enough to work
for all those functions.

Previously Crankshaft emitted a generic load for these, now we emit a load of a
named field, guarded by a proto chain check.

LCheckPrototypeMaps now returns the holder, which is for free, because it
already had to check its map as the last step, anyway. This is in sync with what
StubCompiler::CheckPrototype does.

The delete operator always return true in case of indexed property. It
should return false if an indexed property can't be deleted (eg.
DontDelete attribute is set or a string object is the holder).

55e924c595 Fix CNLT regression. 
This happens when a map A with no descriptors in fast_holey_elements
mode first gets some properties, making it share descriptor arrays with
a map B to which it transitions. Then map A transitions elements kind to
dictionary_elements in map C. C stores the empty_descriptor_array in its
own transition array. When adding a property to C, C transitions to D
and shares the descriptors. If D dies, a CNLT clears the transition
array of C, making the descriptor array of A (and thus also of B) shine
through. If a property is now added to an object in state C, it'll inherit
all the properties of A (and B). If those properties had high field indices,
we do not have a large enough backing store for the single newly added
property, and we'll write out of bounds.

ccc827a6f8 Allocate block-scoped global bindings to global context. 
- The global object has a reference to the current global scope chain.
  Running a script adds to the chain if it contains global lexical declarations.
- Scripts are executed relative to a global, not a native context.
- Harmony let and const bindings are allocated to the innermost global context;
  var and function still live on the global object.
  (Lexical bindings are not reflected on the global object at all,
  but that will probably change later using accessors, as for modules.)
- Compilation of scripts now needs a (global) context (previously only eval did).
- The global scope chain represents one logical scope, so collision tests take
  the chain into account.

106a83252d Fix DoDeferredNumberTagU to keep the value in xmm1 instead of xmm0 on x64. 
xmm0 is not saved across runtime call on x64 because MacroAssembler::EnterExitFrameEpilogue preserves only allocatable XMM registers unlike on ia32 where it preserves all registers.

Cleanup handling of shifts: SHR can deoptimize only when its a shift by 0, all other shift never deoptimize.

Fix type inference for i-to-t change instruction. On X64 this ensures that write-barrier is generated correctly.

Safe operations are those that either do not observe unsignedness or have special support for uint32 values:

- >> and << shifts: they perform ToInt32 on left hand side and ToUint32 on right hand side;
- >>> shift: it performs ToUint32 on both inputs;
- stores to integer external arrays (not pixel, float or double ones): these stores are "bitwise";
- HChange: special support added for conversions of uint32 values to double and tagged values;
- HSimulate: special support added for deoptimization with uint32 values in registers and stack slots;
- HPhi: phis that have only safe uses and only uint32 operands are uint32 themselves.

b10d5d7f08 Deoptimization support for accessors. 
Highlights of this CL:

 * Introduced a new opcode in the deoptimizer for a setter stub frame.

 * Added a global setter stub for returning after deoptimizing a setter.

 * We do not need special deopt support for getters, although the getter stub creates an internal frame. The normal machinery works just right for this case, although we generate a stack that can never occur during normal fullcode execution. If this hurts us one day, we can parameterize and reuse the setter deopt machinery.

1ee6c0e30b Improved constructor inlining unit tests. 
Currently we inline functions with different contexts only on ia32, so we have
to move the helper functions for the various contexts to the top level. Further
more, "new Object()" seems to prevent inlining, too, so we us a simple object
literal.

Although things get consistently inlined now, something strange seems to happen
in test/effect contexts: The DEOPT output seems to contain too few frames, and
we don't get any DEOPT ouput after the first time for those contexts. This has
to be investigated...

f9aea9fcef Inline simple setter calls. 
Currently only simple setter calls are handled (i.e. no calls in count
operations or compound assignments), and deoptimization in the setter is not
handled at all. Because of the latter, we temporarily hide this feature behind
the --inline-accessors flag, just like inlining getters.

We now use an enum everywhere we depend on the handling of a return value,
passing around several boolean would be more confusing.

Made VisitReturnStatement and the final parts of TryInline more similar, so
matching them visually is a bit easier now.

Simplified the signature of AddLeaveInlined, the target of the HGoto can simply
be retrieved from the function state.

83fc4205f6 Fixed compound/count operations with getter-only accessor properties. 
The underlying problem is that for compound/count operations we use the *load*
type feedback for storing, too. For normal properties this doesn't matter, but
for accessor properties we should better use the *store* type feedback, which
would be available, too. This consistent feedback usage could be guaranteed if
we removed the heavy copy-n-paste in the crankshaft code generation for
compound/count operations and assignments/property loads.

To be on the safe side, we postpone this refactoring and do a quick and easily
mergeable fix.

b8a7abd1fc Perform HasFastProperties check on prototypes when computing call targets in Crankshaft, part 2. 
The previous fix was for "real" calls, this one is for getters. It is a bit
unfortunate that this has to be fixed twice: We should really break up
Call::ComputeTarget into a predicate and 1 or 2 getters, so code can be reused.

The regression test has been modified a bit to make things more uniform.

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.

Currently implemented by imul (not fpmul).
x86 and x64 algorithm differs a bit.
x86 implementation is kind of cumbersome, but I couldn't think of better ways.

This changes the compiler to be more aggressive about lazy compilation
of closures with non-trivial outer context. Compilation can only be
triggered with a valid outer context now. One exception is the debugger,
which can request compilation of arbitrary shared code, but it ensures
to trigger compilation only at points where no context is needed.

This relands r11782, r11783, r11790 and a minor fix.

that can be shared.
