Align OD bits for minimal shifting #166

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

The object descriptor fields can be arranged to reduce the amount of shifting 
necessary to access individual fields.

Changed object descriptor bit pattern so .size and .mark fields do not need 
shifting and .type field does not need masking.
Updated some object descriptor macros to reduce checks when od's .free status 
is known.
Updated tools/pmHeapDump.py and pmOdDecoder.py

all tests pass.
