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).

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.

size_t is the correct data type for this purpose. Our APIs (in particular
ExternalSourceStream::GetMoreData) are already using it, and there were some
static_casts to convert between them.
This CL doesn't intend to fix all of V8, just the minimal sense-making part
around scanner character streams.

The first try failed because I needed to make a better distinction
between clearing ICs according to policy at GC time or unconditional
clearing (say, via %ClearFunctionTypeFeedback).
It was also blocked by an issue in super constructor calls.
This fix (https://codereview.chromium.org/892113002/) needs to land
before checking in this CL.

This enables adding more language modes in the future.
For maximum flexibility, LanguageMode is a bitmask, so we're not restricted to
use a sequence of language modes which are progressively stricter, but we can
express the language mode as combination of features.
For now, LanguageMode can only be "sloppy" or "strict", and there are
STATIC_ASSERTS in places which need to change when more modes are added.
LanguageMode is a bit like the old LanguageMode when "extended" mode was still
around (see https://codereview.chromium.org/8417035 and
https://codereview.chromium.org/181543002 ) except that it's transmitted through
all the layers (there's no StrictModeFlag).

For exception in promise we generate v8::Message API object from exception object. And in cases of Syntax or Reference Error we don't have enough information in exception object - we can't restore Error location from top stack frame.
In this patch three aditional private fields introduced for exception object. In case of Syntax Error we store line, column and script on Exception object and receive this information when restoring message.
