mstarzinger@chromium.org [Tue, 2 Apr 2013 17:34:59 +0000 (17:34 +0000)]
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".

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.

Always mark the entire valid prefix of the descriptor array.

Previously we would only mark the slot that was added specifically for
this map, if there was a backpointer and the descriptor array was shared
via the backpointer. However, ConvertTransitionToMapTransition may break
this link after we marked the transitioned map, before we marked the
transitioning map. So the descriptor slots of the parent map won't get
recorded, and we potentially point to an old address of an already
relocated function.

to unwind all JS frames.

* V8::CancelTerminateExecution() -- When execution is terminated via a call
  to V8::TerminateExecution(), this method can be called to clear the
  termination exception so that the engine can continue to be used.

* TryCatch::HasTerminated() -- When a TryCatch has caught a termination
  exception, HasTerminated() will return true to indicate it is valid to
  call V8::ResumeExecution() if desired.

A test case is added to cctest/test-thread-termination.cc.

MIPS: Implement many KeyedStoreStubs using Crankshaft

Port r14001 (28443693)

Original commit message:
- Addition of a compiled hydrogen stub for KeyedStores.
- Inlining of "grow" stubs into OPTIMIZED_FUNCTIONs
- Addition of new "ignore OOB" ic stub that silently swallows out-of-bounds stores to external typed arrays.
- Addition of new "copy-on-write" ic stub that inlines allocation and copying operations for cow array
- New stub are generated with Crankshaft, so they are automatically inlined into OPTIMIZED_FUNCTIONs
