The generated snapshot just crashes on the device, but
disabling snapshots allows us to run V8 just fine which
is sufficient for our purposes at this point.
Mojo/Sky are GN-only so we depend on the V8 GN build even if
it's not considered production for Chromium yet.

- Move NodeMarker to its own file, and introduce a non
templatized base class.
- Cleanup the include hell.
- Sanitize the Node construction methods now that we
got rid of that GenericNode/GenericGraph stuff.
- Protect against NodeId overflow in Graph.
- Various minor cleanups.

The logic was supposed to trigger a rebuild if the CXX variable is
changed. However, it failed to track the other compiler related
variables, and, what is worse, conflicted with the clang=1 gyp setting
by forcing CXX to g++
The new logic just relies on tracking GYP defines, and checks whether
the CXX binary - if set - has a target different from the host
architecture.

Mac OS X 10.9 (Mavericks) has a bug that causes AVX transitions in ISRs,
so we better not use AVX there.

Also support additional number types (singleton ranges, NaN and minus
zero) for constant propagation in typed lowering.

Introduce a new AnyToBoolean simplified operator to handle the later
lowering of boolean conversions. Previously we tried to hack that with
the generic JSToBoolean, having its context set to zero, but that lead
to various problems/bugs and did not handle all cases.

We cannot just clear the result register optimistically, because the
register allocator might assign the same register to result and buffer.

Change InstructionOperand to use a 64-bit field for encoding the operand
information instead of the 32-bit field that was used before. Ideally we
wouldn't use the Zone-allocated bit field at all, and use an integer
instead of the pointer; but that requires fixing the register allocator
first, which will take some time.

We have safe fallbacks in all cases, and it's possible to hit those

Also slightly refactor the NodeCache and CommonNodeCache classes to
