TryInline needed position only for the case when we track positions.
We can drop the position argument and use the current position from GraphBuilder.
The only problem that it doesn't match with the inline point.
The reason of that was the fact that builder had moved the position forward by
visiting arguments expressions.
I fixed this by restoring the current positon in HOptimizedGraphBuilderWithPositions::Visit*

A function could be deoptimized due to a deopt in the inlined code.
The inlined function might be defined in another script. So we need to
track the information about the inlined functions (scriptId and offset).
We already have the tracking code which is behind FLAG_hydrogen_track_position.
So as the first step we need to make the info accessible by CPU profiler.
In the follow-up patches I'll add the code which will enable position
tracking and push the info into CodeEntry entries.

Parser must be able to operate independent of Isolate and the V8 heap during
parsing. After the heap-independent phase, there is a heap dependent phase,
during which we internalize strings, handle errors, etc.
This makes Isolate (also via CompilationInfo) unaccessible during parsing, and
thus decreases the probability of accidental code changes which would add
heap-dependent operations into the heap-independent phase.
Since Isolate is also accessible via CompilationInfo, now CompilationInfo is
only passed to the entry points of parsing, and not stored in Parser.

Use a fake code stub instead, basically following the null object pattern.

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).

It doesn't do anything for now, but it implies strict mode. Added tests to
test-parsing.cc to test that.

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).

If a (pure) node has two or more uses, but there exists a path from the
common dominator of these uses to end, which does not contain a use,
then we split the node such that no unnecessary computation takes place.
Note however, that this only applies if the node cannot be hoisted out
of a loop.

In DevTools we need one more flag for script origin - is debugger script. We already have "is shared origin" flag. The new flag added by analogy with the old but new has accessor in script object.

Along the way:
- Thread isolate parameter explicitly through code that used to
rely on getting it from the zone.
- Canonicalize the parameter position of isolate and zone for
affected code
- Change Hydrogen New<> instruction templates to automatically
pass isolate

of running a script is really spent in compilation. That is, sum up the
total time spent compiling (parsing + compile proper) within a run call
as seen through the API.
@jochen: So many questions:
- Is it ok to re-use V8.CompileLazy?
This measures something a little different.
- clang-format does funny things to the huge macro definitions.
I accepted clang-format changes for all code, but reverted for
the #define orgies in counters.h. ok?
- Am I measuring the right thing. That is, are Aggregat[ing|ed]TimerScope
in the right place?
I'll fiddle a bit more with this to see if it does the right thing. Would
be happy if you could still review now-ish.

This ensures that we always have a kind of "brace" around the actual compilation
with --trace-opt. Previously this was coupled to --trace-hydrogen for
Crankshaft, and there was no output at the start of the compilation for
TurboFan.
Removed redundant "[completed...]" output: Whenever the compilation was
successful, we have already printed "[optimizing...took...]".
Output total TurboFanning time with --trace-opt, too (basically as graph
building time, this is rather arbitrary).
