iposva@google.com 083c9e5e95 - Remember the fact that an object has been added to the 
store buffer by a bit in the header.
- This bit can be used to filter out redundant additions
  into the store buffer making the dedup sets not needed.
- Remove the need for a HashSet when remembering old to
  new references.

regis@google.com 8c44be4313 Add support for object pool that will be used on ARM and MIPS architectures. 
Modify code patching infrastructure to accept code object, which is necessary to
get to the object pool containing patchable target addresses.
Modify assembler test infrastructure to provide associated code object.
