This required fixing the exports_ hash map to use the appropriate
comparison function instead of pointer comparison.

For now we just use the RawMachineAssembler, this will be changed
later to use the whole TurboFan pipeline.

This also adds a new VariableMode, IMPORT, which will be
used to do appropriate binding for Import-declared Variables.
Only named imports are handled for now. "import *" and default
import syntaxes have had their TODOs adjusted to match the new
code structure.

This reverts commit b57be748b1 and
disables the test/mjsunit/debug-clearbreakpointgroup.js because
BreakLocationIterator::ClearBreakPoint is already broken for unrelated reasons (see v8:3924).

When a field type is a map, it is wrapped in a weak cell upon storing to the descriptor array.
Map::GetFieldType(i) does the unwrapping.

The FunctionLiteral returned from the parser for modules now has a MODULE_SCOPE,
instead of associating the module scope with a Block inside it. This makes
it easy to get at the ModuleDescriptor from the caller of Parse(), so I've added
a basic test that pokes at the scope and the descriptor. Expect more tests
in this vein.

Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. The bulk of the changes are to remove some
hard coded assumptions about heap page size within existing tests.
The remaining change is to use a larger heap page size for PPC linux
as this provides a performance benefit due to the larger memory page size.

Add() becomes AddLocalExport, which takes an export_name and a local_name.
New parsing tests exercise this.
Also start generating exports for default exports (though this doesn't yet
handle anonymous default exports).

The root of problem is the fact that we don't track the position of 'this' statement but use them when visit compare statement.
As a result we have -1 as the position of left expression and the resulting relative position is negative and doesn't fit into BitField.

This gets Variable and VariableProxy out of the business of worrying about
Interfaces.
At the same time, get rid of the notion of "module variables". In ES6, variables
that refer to modules will be simply be CONST bindings to module namespace
objects.
The only change in logic here is one more early error:
duplicate export names are now rejected.

This adds a new ControlFlowOptimizer that - for now - recognizes chains
of Branches generated by the SwitchBuilder for a subset of javascript
switches into Switch nodes. Those Switch nodes are then lowered to
either table or lookup switches.
Also rename Case to IfValue (and introduce IfDefault) for consistency.
