19312c1631 Do not clear stepping after DebugEvaluate. 
Clearing stepping was originally introduced in http://codereview.chromium.org/7889039
But DebugEvaluate now also uses a DisableBreak scope, which makes sure we don't step
inside the evaluated code.

cf07add227 Don't create debug context if debug listener is not set 
If there had been no debug listener v8::Debug::GetDebugContext would have created new context and wouln't have kept reference to it. This way we may well end up with several debug contexts and disabled debugger.

As a side effect this change allows to efficiently distinguish debug context from blink contexts by simply comparing handles.

90cbede588 Move prototype metadata from internal properties to prototype maps 
The motivation is that we prefer to avoid creating internal properties, and we have a usable field on maps ("transitions", which is not used for prototype maps).
This CL also ensures the invariant that prototype maps are never shared, even if they are in dictionary mode.

38a719f965 Switch full-codegen from StackHandlers to handler table. 
This switches full-codegen to no longer push and pop StackHandler
markers onto the operand stack, but relies on a range-based handler
table instead. We only use StackHandlers in JSEntryStubs to mark the
transition from C to JS code.

Note that this makes deoptimization and OSR from within any try-block
work out of the box, makes the non-exception paths faster and should
overall be neutral on the memory footprint (pros).

On the other hand it makes the exception paths slower and actually
throwing and exception more expensive (cons).
