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).

Original commit message:
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.

Port 5d68529b

Original commit message:
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.

It's unnecessary; PreParser can just use normal Scopes for the things it needs
to track. Note: the only functionalities of PreParserScope were keeping track of
the scope stack, and for each scope, the scope type and language mode. Those are
now done by Scope. PreParser doesn't yet put variables into scopes (that will be
done in a follow up).

Several tiny changes for the upcoming TurboFan-genrated handlers/stubs:

   * Relaxed the type of code_stub().

   * Made GetCodeKind() public, it effectly was like this, anyway.

   * Const-corrected GetStubType().

original commit message:

   Externalize deoptimization reasons.
   1) The hardcoded strings were converted into DeoptReason enum.

   2) Deopt comment were converted into a pair location and deopt reason entries so
      the deopt reason tracking mode would less affect the size of the RelocInfo table and heap.

   3) DeoptReason entry in RelocInfo reuses kCommentTag value and generates short entry in RelocInfo table.
