1311b8f0e2 Improve Hydrogen code for accessing undefined/null/Infinity.
In some special (but probably very common) cases we can do better than loading
from a global cell for these global properties by emitting the corresponding
constant directly. This opens up opportunities for further improvements, coming
in a separate CL...

This avoid unwanted sharing between different function prototypes and in

0f682143d9 Introduce code flushing of RegExp code.
Due to issues relating mostly to chrome extensions we have lately been
running into OOMs that are caused by our executable space running
out. This change introduces flushing of code from regexps if we have
not used the code for 5 mark sweeps.

The approach is different from the normal function code flusing. Here
we make a copy of the code inside the data array, and exchange the
original code with a smi determined by the sweep_generation (a new
heap variable increased everytime we do mark sweep/compact). If we
encounter a smi in EnsureCompiled we simply reinstate the code
object. If, in the marking phase of mark sweep, we find a regexp that
already have a smi in the code field, and this is more than 5
generations old we flush the code from the saved index.

7d2be7c0e0 Support debugger inspection of locals in optimized frames
Optimized frames are now handled by the debugger. When discovering optimized frames during stack inspection in the debugger they are "deoptimized" using the normal deoptimization code and the deoptimizer output information is used to provide frame information to the debugger.

Before this change the debugger reported each optimized frame as one frame no matter the number of inlined functuions that might have been called inside of it. Also all locals where reported as undefined. Locals can still be reposted as undefined when their value is not "known" by the optimized frame.

As the structures used to calculate the output frames when deoptimizing are not GC safe the information for the debugger is copied to another structure (DeoptimizedFrameInfo) which is registered with the global deoptimizer data and processed during GC.

5e7da7f04f Remove the fcontext field from all contexts.
Before: every context cached the nearest enclosing function context.  This
assumed that for nested contexts (i.e., with and catch contexts) the
enclosing function had a materialized link in the context chain.

Now: when necessary, we loop up the context chain to find such a context.
This enables catch contexts without forcing the enclosing function to
allocate its own context.

7d527f857f Change the representation of catch contexts.
Before, they had no extra slots and an extension object with one named
property.  Now, they use the extension slot for the property name and have
an extra slot for the thrown object.  This increases the size of the context
itself, but removes overall allocation and eliminates a level of indirection.

4b96218589 Link function contexts directly to the previous context.
Instead of NULL in the previous field of function contexts, put the previous
context.  This saves the indirection of fetching the previous through the
context's closure.

371af773cf A collection of context-related refactoring changes.
Introduce separate maps for function and with contexts.  Use the function
context map for testing whether a context is a function context (global
contexts are no longer function contexts).

Split the paths for allocating with and catch contexts.

Rename some functions.  Generally refactor code to make it simpler.
