add and update exp files for drd/tests/annotate_trace_memory

exp-32bit files needed minor update for the last store, and some mips32
platforms also need additional exp-mips32 due to different way of loading
and storing double values.

This fixes drd/tests/annotate_trace_memory on different 32-bit platforms.
