Mechanical change.
This will break dependency between profiler-generator and heap-profiler-generator.
Later this will help us to reuse SourcePosition in cpu-profiler.

ModuleDescriptor will end up holding the set of data described in the
spec as a "Module record". This introduces a little bit of confusion
with ModuleInfo, but I hope that'll become clearer over time.
Also removed the interface-printing flags. We probably want
Module-printing flags, but that can wait until we have more
Module-related structures.

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.

Function.prototype.toMethod was removed from ES6.
This removes the function and updates the tests to either
use %ToMethod or a dedicated syntax (using concise method
or a class).

Contribution of PowerPC port (continuation of 422063005 and 817143002). This patch covers
the key changes needed to the common files needed to support AIX. Subsequent
patches will cover:
- changes to update the ppc directories so they are current with the changes
in the rest of the project.
- remaining AIX changes not resolved by 4.8 compiler
- individual optimizations for PPC

This relands the CL
https://codereview.chromium.org/797503007/.
It runs the version generation two times. First during
runhooks as a fallback for recipes that loose git context
(e.g. android_aosp). Second during compilation like in the
original CL. In case of failures, the result from the
runhooks call will be reused.

- Make Node::Inputs and Node::Uses mostly STL compliant.
- Get rid of some pre-C++11 crappiness.
- Start moving unit tests from cctest to unittests.
- TrimInputCount() now tries to reserve inputs slots for
later appending.
- Fix numerous style guide violations.

- 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.

Also slightly refactor the NodeCache and CommonNodeCache classes to
reduce inherent overhead of caching.

The CommonOperatorReducer currently takes care of redundant Phis,
EffectPhis and Selects. This functionality overlaps with ControlReducer,
but is required to make certain optimizations effective, since the
ControlReducer only runs really early and really late in the pipeline
and therefore other reducers aren't reapplied properly after redundant
phi/select elimination.

This is an initial version of redundant load elimination, currently
limited to LoadField operators, and implemented by walking the effect

Because of this, every time we build the host toolset, snapshot_blob_host.bin is not found. This causes the target (v8_external_snapshot) that generates such file to be run. This target generates snapshot_blob.bin instead of snapshot_blob_host.bin. This in turn causes all the targets that depend on snapshot_blob.bin to run again.
After this, we still don't have snapshot_blob_host.bin. So the next time we build, the whole process described above happens again.
