While the number definition for JavaScript is double-precision. We use

Parser & internalizing: efficiency fixes.

1) In ParseLazy, we're already using the heap, so we can also tell
AstValueFactory to internalize immediately. This is more efficient.

2) No need to collect the values in values_ and strings_ if they're already
internalized.

3) No need to collect AstValues which are strings in values_ since they don't
need to be internalized (the underlying strings will be internalized
separately).

[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).

Clear old backing store of WeakCollection on updates.

Not clearing can lead to a crash under following conditions:
1. Backing store of a weak map is allocated in large object space.
2. The backing store is marked incrementaly via the weak map.
3. The weak map is updated and gets a new backing store.
4. The store buffer overflows and marks the chunk of the old backing store as
"scan on scavenge."
5. Mark-compact collection kills some elements of the weak map. Note that the
old backing store survives because it was marked incrementally, but its dead
elements are not cleared.
6. Scavenger iterates over the old backing store, tries to move a dead object
and crashes.

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
https://codereview.chromium.org/7739020.
