The legacy function declaration locations from Annex B 3.2 and 3.4 do not
apply for generator declarations. This patch cracks down on those usages,
which is tested for by new incoming test262 tests.

This makes sure that the testing pipeline withing the FunctionTester
class only performs AST analysis and deoptimization preparation when
graphs are generated from the AST (as opposed to from bytecode).

This commit introduces IgnitionStatisticsExtension, which provides
methods for accessing Ignition statistics and counters from JavaScript.
The extension is registered when FLAG_ignition and
FLAG_trace_ignition_dispatches are both enabled.
For the moment, the only exposed function is
getIgnitionDispatchCounters(), which allows to retrieve Ignition
dispatch counters as a JavaScript object.

Between the miss and patching, we run user code. That may already patch the same code. IC refactoring broke this (again), so including a regression test this time around.

This adds a new ignition_turbofan testing variant that'll
allow switching turbofan off in the other ignition variant.
The switch will happen in a follow up after reconfiguring
the bots.

The first version of --harmony-for-in avoided throwing PreParser
errors in order to retain use counting. This patch threads
use_counts_ through to the PreParser to allow use counting in
the PreParser while also throwing errors for this case.
Also slightly refactored the Parser code to do a little less
code duplication.

If the target is deprecated, the object will be updated on first store. If the source for that store equals the target, this will invalidate the cached representation of the source. Preventively upgrade the target.

These also lower to subgraphs that have to be connected to the effect
and control chains, otherwise removing the atomic regions around heap
allocations would still be unsound.

This will allow to pull in gyp as a deps to the same location
as chromium (tools/gyp not build/gyp), needed for gn switch.
This is the first step of a 3-way move.
1) Copy v8.gyp in v8
2) Update references in embedders (follow up)
3) Remove old v8.gyp (follow up)

This allows us to get rid of the "push TruncateFloat64ToInt32 into Phi"
trick that was used in the MachineOperatorReducer to combine the
ChangeTaggedToFloat64 and TruncateFloat64ToInt32 operations. Instead of
doing that later, we can just introduce the proper operator during the
representation selection directly.
Also separate the TruncateFloat64ToInt32 machine operator, which had two
different meanings depending on a flag (either JavaScript truncation or
C++ style round to zero). Now there's a TruncateFloat64ToWord32 which
represents the JavaScript truncation (implemented via TruncateDoubleToI
macro + code stub) and the RoundFloat64ToInt32, which implements the C++
round towards zero operation (in the same style as the other WebAssembly
driven Round* machine operators).
