a6a7c75ae0 MIPS port initial commit 
This is the first step in the MIPS port of V8. It adds assembler, disassembler and simulator for the MIPS32 architecture.

Contains stubbed out implementation of all the compiler/code generator infrastructure to make it all build.

Patch by Alexandre Rames from Sigma Designs Inc.

This is the landing of http://codereview.chromium.org/543161.

a28143c77c Added extra tests to the DefineOrRedefineAccessorProperty and 
DefineOrRedefineDataProperty to avoid invalid input.

Added tests to object-define-property.js to test that it does not crash 
on invalid input.

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.

048fe9b980 RFC: Try to be much more careful with where we skip the write barrier by: 
1. Avoid using SKIP_WRITE_BARRIER when we don't have to (smis).
  2. Check and document the remaining uses of SKIP_WRITE_BARRIER.
  3. Only allow GetWriteBarrierMode when in an AssertNoAllocation scope.

The only functional change should be in DeepCopyBoilerplate where we
no longer use the write barrier mode (because of allocations). I'm
running benchmarks to see if this has a measurable impact on performance.
