A CompilationInfo constructed from just an Isolate* and a Zone* is in
weird an inconsistent state (calling e.g. flags() on it will crash),
so we need to avoid them. This CL removes almost all of them, the
remaining 2 call sites in (for testing only) will be handled in a
separate CL. Things which have been changed:
* Linkage is basically a decorator for CallDescriptor now.
* ChangeLowering doesn't need Linkage at all.
* JSGenericLowering doesn't need a full CompilationInfo*, just a
single flag.
* JSContextSpecializer doesn't need the full CompilationInfo, just a
Context.
* Removed unused CompilationInfo from SimplifiedLoweringTester.
This nicely decouples things already a bit more, but there's still
work to do...

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).

super() is only allowed in a class constructor.
super.p is allowed in methods, accessors and constructors.
The parser now checks the FunctionState to see what kind of function
we are currently inside.

Adding the line "// MODULE" to an mjsunit file will now cause
run-tests.py to prefix the test case with "--module" in the
d8 commandline.
d8 has itself been updated to treat files preceded with "--module" as
modules (that is, it compiles them with ScriptCompiler::CompileModule,
and turns on --harmony-modules).

To do so, extract startup_data_util from d8 and use it those executables.

Scope, like Parser, must be able to operate independent of Isolate and the V8
heap (for background parsing). After the heap-independent phase, there is a heap
dependent phase, during which we do operations such as scope anaylysis.
This CL makes the phases explicit by not telling Scope about the Isolate too
early (during the heap-independent phase, Scope should know nothing about
Isolate). This decreases the probability of accidental code changes which would
add heap-dependent operations into the heap-independent phase.

1) Deoptimizer::Reason was replaced with Deoptimizer::DeoptInfo
because it also has raw position. Also the old name clashes with DeoptReason enum.
2) c_entry_fp assignment call was added to EntryGenerator::Generate
So we can calculate sp and have a chance to record the stack for the deopting function.
btw it makes the test stable.
3) new kind of CodeEvents was added to cpu-profiler
4) GetDeoptInfo method was extracted from PrintDeoptLocation.
So it could be reused in cpu profiler.

We incorrectly disallowed eval and arguments in accessor and method
names. This was because we checked the name inside the
ParseFunctionLiteral. We now flag accessors so that lazy parsing of
these functions are treated correctly.

This adds an "experimental" API hook (v8::ScriptCompiler::CompileModule)
allowing compilation of modules. The code gen is incredibly basic: the
module body is represented by a Block in the AST. But this at least gets
more of the pipeline working, and opens the door to writing mjsunit tests
(once d8 is modified to support module compilation).

Previously it just had hacks to have NULLs instead of them and pretended to know
nothing about Zone. The hacks provide no real benefit (probably historically
based on some weird misconception about the relationship between Zone and
Isolate), and make it harder for the PreParser to start to know more about
variables and scoping.

Contribution of PowerPC port (continuation of 422063005, 817143002 and 866843003)
This patch brings the ppc directories up to date with our repo. We have
removed 5 individual optimizations which require changes in both the ppc and common
directories so they can be more easily reviewed on their own in subsequent patches.
Subsequent patches will cover:
- individual optimizations for PPC (5)
- remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available
for AIX)
- incremental updates required to ppc directories due to platform specific changes
made in google repos while we complete the above steps.
With the update there are still some timeouts seen when run in simulated mode which
may be a result of the missing optimizations. Once we have the optimizations in
we will review the simulation results and address/exclude tests as necessary so that
the simulated runs are clean.
