df0cb9999f Parsing: Make Parser not know about Isolate during background parsing.
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.

70079dab13 Add basic compilation support for modules
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).

c7851da4ae Introduce LanguageMode, drop StrictMode.
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).

d8cfbc633d [turbofan] Split pure nodes in the scheduler if beneficial.
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.

6f9d60cc6f Implement AggregatableHistogramTimer and use it to measure how much time
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.

50b7ca5593 Improved --trace-opt output a bit.
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).

71bb00e261 Consistently use only one of virtual/OVERRIDE/FINAL.
FINAL implies OVERRIDE, which in turn implies virtual, so there's no need to use
more than one of these. The Google C++ style guide even requires this, see
http://google-styleguide.googlecode.com/svn/trunk/cppguide.html#Inheritance.

While we're here, port r24662 to x87.

The net result is that v8 compiles again with a current clang.

9da4998204 Abort optimization in corner case.
The %OptimizeFunctionOnNextCall sledgehammer can cause a function to be
marked for optimization before it's ever been compiled by fullcode.
This can lead to the situation where a function doesn't have optimization
disabled until we try to compile it optimized.

Basically, the assert should just handle this case more gracefully.
