123500999f Reland 7917:
Better support for 'polymorphic' JS and external arrays

Allow  keyed store/load stubs to switch between external array and fast JS arrays without forcing a state transition to the generic stub.

There CL consists of two pieces of functionality. First, code stubs for fast element arrays don't immediately transition to the MEGAMORPHIC state when there's a map mismatch. Second, two ICs are cached per map for fast elements, the MONOMORPHIC version, and a new MEGAMORPHIC version that handles two or more different maps and dispatches to shared stubs to perform the array operation.

Second, two ICs are cached per map for fast elements, the MONOMORPHIC version, and a new MEGAMORPHIC version that handles two or more different maps. Currently, the only array types supported by the MEGAMORPHIC stub are fast elements for objects and JSArrays.

d0fcbb4ece Simplify include dependencies.
Try to make sure that accessors.h, data-flow.h, list-inl.h, and
scopeinfo.h are included only where needed, but without introducing
implicit dependencies.

ec58c05f4e Add support for startup data (snapshot) compression.
This is for mobile platforms where application footprint size is
important. To avoid including compression libraries into V8, we assume
that the host machine have them (true for Linux), and rely on embedder
to provide decompressed data.

Currently, only snapshot data can be comressed. It is also possible to
compress libraries sources, but it is more involved and will be
addressed in another CL.

af7b6fecfe Split globals.h into two parts, where only one depends on V8.
Made allocation.{h,cc} independent of V8, allowing utils.h to allocate
vectors and collectors.

9c503a8330 Fix some inconsistent formatting.
I noticed we sometimes had extra spaces before and after the "const"
keyword.  Probably the result of a search and replace gone wrong.

This is a whitespace only change.

d53f05e3e2 Fix warnings on Win64.
Set warning level to /W3 and change implicit conversions from size_t
to int. Most "fixes" are simply manifesting the implicit casts or using
a special strlen replacement that returns int.

d03c277f5e Changed saved context stack to using direct pointers. Before we would
create a new persistent handle to hold the context to save when
entering another context, now we use a stack of direct pointers that
the gc knows about.

30a0a7de43 Split nested namespaces declaration in two lines in accordance with C++ Style Guide.
This issue was raised by Brett Wilson while reviewing my changelist for readability. Craig Silverstein (one of C++ SG maintainers) confirmed that we should declare one namespace per line. Our way of namespaces closing seems not violating style guides (there is no clear agreement on it), so I left it intact.

e37f6087c6 In List::Add, correctly handle the case of adding a reference to a
preexisting list element to a list, and to not return anything (we
never used the return value).  Remove List::Insert, it is not
currently used or needed.  Change List::AddBlock to take a copy of
the element to be replicated rather than a reference.
