7af6883098 Fixed deoptimization of inlined getters. 
It is necessary to explicitly handle the internal frame lying between the caller
of the getter and the getter itself in the deoptimizer: When the getter is
inlined, leaving the internal frame restores the correct context.

5330f5b24f Check the return value of API calls on ia32 and x64. 
This implies that the return value of native getters is checked. The nice part
is that one can even see the name of the property in question in the abort
output when the check failed.

Under some circumstances even the return value of interceptors gets checked, but
I'm not 100% sure about this, because the interceptor code is basically tuned to
death.

The change seems to have very low overhead, so it might be feasible to keep this
check enabled unconditionally.

This prevents a corner case in FindSharedFunctionInfoInScript that would cause
functions to be optimized because an intermittent GC would clear the flag
indicating whether breakpoints are present. Above method was also moved into the
Debug class because it is only used by the debugger.

ccc827a6f8 Allocate block-scoped global bindings to global context. 
- The global object has a reference to the current global scope chain.
  Running a script adds to the chain if it contains global lexical declarations.
- Scripts are executed relative to a global, not a native context.
- Harmony let and const bindings are allocated to the innermost global context;
  var and function still live on the global object.
  (Lexical bindings are not reflected on the global object at all,
  but that will probably change later using accessors, as for modules.)
- Compilation of scripts now needs a (global) context (previously only eval did).
- The global scope chain represents one logical scope, so collision tests take
  the chain into account.

The reason for disabling optimization of a given function is carried around in
CompilationInfo. The new mechanism is general enough that --trace-opt now
subsumes everything --trace-bailout could print, so we nuked the latter flag.
