Fix worst-case behavior of MergeRemovableSimulates().

Currently, when a long series of removable simulates are merged, we do
this by merging them one by one as we find them. As we merge the value
value lists of the simulates, those lists snowball so that we get a
quadratic complexity wrt runtime and memory consumption.

Instead, we gather simulates that need to be merged, and merge them
backwards starting from the last simulate.

Refactor parser mode configuration for correctness

This patch refactors the parser and preparser interface to be more
readable and type-safe.  It has no behavior changes.

Previously, parsers and preparsers were configured via bitfield called
parser_flags in the Parser constructor, and flags in
PreParser::PreParseProgram, ParserApi::Parse, and ParserApi::PreParse.
This was error-prone in practice: six call sites passed incorrectly
typed values to this interface (a boolean FLAG value, a boolean false
and a boolean true value).  None of these errors were caught by the
compiler because it's just an "int".

The parser flags interface was also awkward because it encoded a
language mode, but the language mode was only used to turn on harmony
scoping or not -- it wasn't used to actually set the parser's language
mode.

Fundamentally these errors came in because of the desire for a
procedural parser interface, in ParserApi.  Because we need to be able
to configure the parser in various ways, the flags argument got added;
but no one understood how to use the flags properly.  Also they were
only used by constructors: callers packed bits, and the constructors
unpacked them into booleans on the parser or preparser.

The solution is to allow parser construction, configuration, and
invocation to be separated.  This patch does that.

It passes the existing tests.

Add parser support for generators.

This patchset begins by adding support for "yield", which is unlike other tokens
in JS. In a generator, whether strict or classic, it is a syntactic keyword.
In classic mode it is an identifier. In strict mode it is reserved.

This patch adds YIELD as a token to the scanner, and adapts the preparser and
parser appropriately. It also parses "function*", indicating that a function is
actually a generator, for both eagerly and lazily parsed functions.

Currently "yield" just compiles as "return".

MIPS: Change LookupForWrite to always do a full lookup and check the result.

Port r14061 (df49702a)

Original commit message:
If we find a property in the prototype-chain that we can overwrite, and
we have a transition, keep the holder in the lookup-result as the actual
holder. We will need it for the consistency-check in GenerateStoreField.

By directly checking the entire chain we avoid having to lazily bail out
to a copy of the miss stub while generating the Field Store IC.

Currently this CL disallows a normal non-receiver holder, given that
that would require a positive lookup + details verification to ensure
the property did not become read-only. This fixes the regressions in the
attached tests.

Fix crash involving zombie maps escaping from the JSON parser's underground lab

Zapping is required since transition arrays contain weak references to maps: At the end of a GC cycle, ClearNonLiveTransitions removes references to dead maps from transition arrays. If a marked transition array with weak (dead) references is replaced by another transition array before the end of the GC cycle, dead references are not removed from the replaced transition array. If the replaced transition array is kept alive by a handle, marking will crash when trying to mark the first reference to a dead map.

- Remove symbol_delegate and GetDelegate function.

Fix %GetArrayKeys to not skip non-enumerable indices

This is one step in the direction of fixing a range of small bugs in the array methods when dealing with non-standard element attributes.

Added tests exercising this behavior for shift and unshift.

For Proxies and Interceptors, the behavior of %GetArrayKeys is now to just return an interval, rather than trying to list all their indexed properties. In the Proxy case, this seems like the only way to avoid an observable difference between smart and non-smart array methods. For Interceptors, the usual case (in WebKit, anyway) is for them to have all indices in [0, length), so enumerating them won't be any better than simply iterating over that range.
