[turbofan] Do not use the generic graph algorithm for widening in the typer.
This change uses an explicit queue for type-widening instead of the
generic algorithm. The trouble with the generic algorithm was that it
called the visitor on the same phi many times in a row (and thus caused
unnecessary retyping). I also think that the queue-based fixpoint is
more readable.
The CL cuts running time of the nbody-java benchmark from ~19s to ~15s,
the time spent in the typer goes from 4.5s to 1s. This is still a lot
- the root cause appears to be slow handling of union subtyping
(m*n for unions of sizes m and n). I see a re-typing of a
single phi node taking > 100ms. I will work on a fix with Andreas,
hopefully we can come up with some canonical representation
of unions at least for the common cases (union of Smi constants).
I have also changed the initial typer run to always compute a type, even
if we already had a type for the node. This fixes one assert failure
where context specialization updates a node without updating the type,
which confuses the typer when widening (as some types suddenly narrow).

Scanner: remove PushBack calls when we're going to return ILLEGAL.
This simplifies escape handling and makes it easier to extend escapes for ES6.
PushBack just before detecting ILLEGAL is unnecessary, since we will abort the
scanning / parsing anyway at that point, and it doesn't matter where the cursor
exactly is. The error messages w/ PushBack are not any better or more correct
than without.
In addition: remove a comment about handling invalid escapes gracefully when we
no longer do. (*)
This CL includes a behavioral change: For input "var r = /foobar/g\urrrr;" we
used to report "unexpected_token: ILLEGAL" for "\u", but now we report
malformed_regexp_flags which is a more correct error message. (Note that the
code for reporting invalid_regexp_flags was dead, and invalid_regexp_flags is
not the right error message.)
Note that the V8 is more relaxed about unicode escapes in regexp flags than ES6
(see
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-regular-expressions )
and this CL doesn't change it. (V8 accepts any \uxxxx, ES6 spec says only a
certain value range is acceptable.)
(*) Code archaeology:
Originally, doing PushBack in ScanHexEscape made sense (see e.g., here
https://codereview.chromium.org/5063003/diff/6001/src/prescanner.h ), since we
wouldn't return ILLEGAL but treat an invalid escape sequence "\uxxxx" as
"uxxxx".
(The repo at that point contains another instance of the same function, from the
initial commit. The logic is the same.)
This behavior was changed in a "renaming" commit

EmitCreateIteratorResult loads map from function's context
Caching or serialization can cause full-codegen output to be shared

Various cleanup/simplification in object-observe.js
The biggest change is the removal of the map wrapper objects:
we now operate directly on the observation weak map, since there
are already Get/GetOrCreate/Set functions for each info map.
Various other small cleanups as well, including the deletion of
unnecessary forwarding functions and making use of standard macros.
This is a reland of r24972, retaining GetObservationStateJS() to
keep snapshotting working properly.

Run ControlReducer early after graph building, then again later.
The justification for doing this is to reduce the size of the graph and
therefore speedup later phases of compilation. The control reducer also
obviates the need to run the PhiReducer, since it subsumes it.
