f6cd2403e3 Fix deoptimizer for shared optimized code. 
The deoptimizer searched the stack for activations of the same function to
determine whether to trigger lazy deopting. Since we share optimized code we
actually need to search for activations of the same code (but potentially
different functions).

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.

74aa15bfa0 Fix FindSharedFunctionInfoInScript to not optimize. 
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.

106a83252d Fix DoDeferredNumberTagU to keep the value in xmm1 instead of xmm0 on x64. 
xmm0 is not saved across runtime call on x64 because MacroAssembler::EnterExitFrameEpilogue preserves only allocatable XMM registers unlike on ia32 where it preserves all registers.

Cleanup handling of shifts: SHR can deoptimize only when its a shift by 0, all other shift never deoptimize.

Fix type inference for i-to-t change instruction. On X64 this ensures that write-barrier is generated correctly.

f476d4d431 Allow uint32 value on optimized frames if they are consumed by safe operations. 
Safe operations are those that either do not observe unsignedness or have special support for uint32 values:

- all binary bitwise operations: they perform ToInt32 on inputs;
- >> and << shifts: they perform ToInt32 on left hand side and ToUint32 on right hand side;
- >>> shift: it performs ToUint32 on both inputs;
- stores to integer external arrays (not pixel, float or double ones): these stores are "bitwise";
- HChange: special support added for conversions of uint32 values to double and tagged values;
- HSimulate: special support added for deoptimization with uint32 values in registers and stack slots;
- HPhi: phis that have only safe uses and only uint32 operands are uint32 themselves.

b10d5d7f08 Deoptimization support for accessors. 
Highlights of this CL:

 * Introduced a new opcode in the deoptimizer for a setter stub frame.

 * Added a global setter stub for returning after deoptimizing a setter.

 * We do not need special deopt support for getters, although the getter stub creates an internal frame. The normal machinery works just right for this case, although we generate a stack that can never occur during normal fullcode execution. If this hurts us one day, we can parameterize and reuse the setter deopt machinery.

42552808ab Rename "global context" to "native context", 
in anticipation of the upcoming lexical global scope.

Mostly automatised as:

for FILE in `egrep -ril "global[ _]?context" src test/cctest`
do
  echo $FILE
  sed "s/Global context/Native context/g" <$FILE >$FILE.0
  sed "s/global context/native context/g" <$FILE.0 >$FILE.1
  sed "s/global_context/native_context/g" <$FILE.1 >$FILE.2
  sed "s/GLOBAL_CONTEXT/NATIVE_CONTEXT/g" <$FILE.2 >$FILE.3
  sed "s/GlobalContext/NativeContext/g" <$FILE.3 >$FILE
  rm $FILE.[0-9]
done

f5f8ebd4ed Fix accessor lookup in crankshaft. 
Seeing monomorphic type feedback plus an AccessorPair does not necessarily imply
that the corresponding getter/setter is really there, so we have to check for
this explictly.

886c0fa4f7 Extend constructor inlining test case. 
This makes sure that deoptimization really happens in each hydrogen
context by not using binary operations but loads instead. This is
needed because we cannot clear BinaryOpICs explicitly.
