9b5c312bfc Initial implementation of fast path operation for bitwise OR. 
Support a binary operation (bitwise OR) so long as it's not nested in
the left subexpression.  This ensures that the expression stack never
has height greater than two and so can be kept fully in registers.

The bounded expression stack height and the absence of any side
effects on the fast path allows us to still bailout out to the very
beginning of the function if any of our fast-path checks fail.

df1df78c48 Changed fuzzer to randomly remove half of the arguments when running 
on functions that takes five or more arguments. Original version runs
for a long time when there is 5 arguments in a runtime function (45+
seconds). The fuzzer can be run with all arguments on all functions
regardless of the number of arguments by setting
RUN_WITH_ALL_ARGUMENT_ENTRIES to true in fuzz-natives.js

2f0f6face1 Fast compiler: Load globals variables directly from property cells. 
This is a first step towards loading globals directly from property cells instead
of going through a load IC.

This change supports only properties with the DontDelete attribute since
we are only able to bailout into the generic code generated by the secondary 
code generator the beginning of a function. The resulting fast-case code is 
specialized for a specific context. When invoked with a different global object, 
it will always bailout to the secondary code.

When loading a property that does not exist at compile-time or a property
that is deleteable we still generate the generic load IC.

4f179b09ba Added IsProperty() check to result in DefineOrRedefineAccessor - if no check 
this causes the debug check to fails since type() asserts that the 
lookup_type != NOT_FOUND. This does not change any functionality since we 
explicitly checked if it was one of the three types that we need to delete.
Also changed defineProperties in v8natives to actually return the object
being defined (as specified by spec)

f74a08d8ee Added Object.defineProperty + needed internal functionality: 
DefineOwnProperty (changed to allow for redefinition of existing property)
  SameValue
  Extra info on propertydescriptor
  GetProperty
  HasProperty

Currently the DefineOrRedefineAccessorProperty deletes the existing
property on the object if it is a dataproperty (FIELD or NORMAL) and
adds a new one. This can potentially be optimized.

10910394e6 Handle insertion order for simple constructors 
When functions only have simple assignments of the form this.x = ... the object is created in generated code without actually calling the constructor. In this case the initial map for the function already contains the properties assigned in the constructor. The field descriptors in this initial map now has an enumeration index assigned to make property enumeration order the insertion order. The insertion order here is the order of the this.x assignments in the code.
