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.

Revert of [turbofan] Fix bunch of tests failing with --turbo-deoptimization. (patchset #1 id:1 of https://codereview.chromium.org/786333004/)

Reason for revert:
This changes layout test expectations. I ran a bisect over the layout tests:

Bad:
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2032/builds/1600

Good:
http://build.chromium.org/p/client.v8/builders/V8-Blink%20Linux%2032/builds/1599

If this is intentional please first land a CL with manualrebaseline test expectations for the changed tests and then reland.

Two issues:
1) We would trace the MISS two times on vector-based KeyedLoadIC
   with a string key in MEGAMORPHIC state.
2) There was a confusing asymmetry in the handling of going
   GENERIC. This change makes it the same whether
   --vector-ics is on or not.

- 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.

Hopefully we'll catch heap corruption earlier where identifying the
object that holds a stale pointer.

Speaking of staleness, also remove old debugging code.

This time we simply undo the change introduced by the PPC port for
this test. No idea why it should be necessary, and Windows XP
obviously doesn't give us that much stack, anyway.

The test fails on XP only, so let's tentatively raise the stack limit more. We probably need to investigate what a tighter limit might be and (more importantly) what the underlying reason for the failure is.

Hopefully 1800kB is enough, we can't test this via try jobs, because we don't have XP try bots. :-/

Contribution of PowerPC port (continuation of 422063005). The inital patch
covers the core changes to the common files.  Subsequent patches will cover
changes to common files to support AIX and to update the ppc directories so
they are current with the changes in the rest of the project.

This is based off of the GitHub repository

This also simplifies target_stack_ and tightens up the types of nodes
