604672e87f Changing the aging mechanism for script and eval caches. 
Instead of using multiple generations for the code, first only store the hash that gets aged. Once a hash matched on a next probe, actually cache the code. Use regular code aging to remove entries from the cache.

cc960f8034 Revert "RegExp: Add support for the ES6-proposed sticky flag" 
Causes a flaky failure on buildbots. Here is the (deterministic) repro step (thanks to Michael Stanton):

first go to flag-definitions.h and set this to false.

DEFINE_BOOL(enable_sse4_1, false,
            "enable use of SSE4.1 instructions if available")

Run the following and it should fail:

2a4be7067c Refactor the compiling pipeline. 
Goals:
 - easier to read, more suitable identifiers.
 - better distinction between compiling optimized/unoptimized code
 - compiler does not install code on the function.
 - easier to add features (e.g. caching optimized code for osr).
 - remove unnecessary code.

96fc677d25 Pipe a script's CORS status through V8 during compilation. 
In order to properly sanitize exception data during a 'window.onerror'
handler, we need to know whether a script was served with proper CORS
headers at the time it was loaded into V8. This patch adds a single bool
to ScriptOrigin, and pipes that through the compiler to land on the
Script object. We can then retrieve the parameter when calling the
embedder's exception callback.

1e9a7267ab Introduce extended mode. 
This CL introduces a third mode next to the non-strict
(henceforth called 'classic mode') and 'strict mode'
which is called 'extended mode' as in the current
ES.next specification drafts. The extended mode is based on
the 'strict mode' and adds new functionality to it. This
means that most of the semantics of these two modes
coincide.

The 'extended mode' is entered instead of the 'strict mode'
during parsing when using the 'strict mode' directive
"use strict" and when the the harmony-scoping flag is
active. This should be changed once it is fully specified how the 'extended mode' is entered.

This change introduces a new 3 valued enum LanguageMode
(see globals.h) corresponding to the modes which is mostly
used by the frontend code. This includes the following
components:
* (Pre)Parser
* Compiler
* SharedFunctionInfo, Scope and ScopeInfo
* runtime functions: StoreContextSlot,
  ResolvePossiblyDirectEval, InitializeVarGlobal,
  DeclareGlobals

The old enum StrictModeFlag is still used in the backend
when the distinction between the 'strict mode' and the 'extended mode' does not matter. This includes:
* SetProperty runtime function, Delete builtin
* StoreIC and KeyedStoreIC
* StubCache

90c9f1b989 Suspend runtime profiler as soon as we exit JS. 
Lots of web pages have really frequently firing timers that keep the
profiler thread spinning if we require a period of JS inactivity
before suspending the profiler. While it's possible to throttle it by
increasing the sleep delay and adjusting the duration of the required
inactive period, it seemed much simpler to just stop it immediately on
exiting JS.

Stopping the profiler this way effectively turned off two optimization
heuristics: 1) eager optimization (it's reset on waking up the
profiler and now the profiler wakes up much more frequently) and 2)
optimization throttling based on JS to non-JS state ratio (the ratio
is now 100%). I removed these two heuristics and found no performance
regressions so far.

1cbe7a240a Fix two deallocation bugs identified by Coverity Prevent. 
1. The tables array allocated in the CompilationSubCache constructor
   was never deallocated.  Fixed by adding destructor.

2. The buffer allocated in one of the constructors of the
   NoAllocationStringAllocator was never deallocated.  It seems that
   this class sometimes owns the buffer (if it allocated one itself)
   and sometimes doesn't (if it was passed one).  Simple fix is to
   remove the offending constructor which was never used anyway.

9e35fb6582 Lower the number of generations in the script compilation 
cache to 5 (down from 8). Generations 5, 6, and 7 are 
rarely hit in real browsing sessions (~2% in the best case)
so it seems better to lower the size to avoid carrying around 
too many compiled scripts in the cache.
