Implement is_instr_load_store() to detect whether a given instruction
is one of the fixed-point or floating-point load/store instructions.
This function will be used in a follow-on patch to save memory hierarchy
information of the load/store.

perf_mem_data_src is an union that is initialized via the ->val field
and accessed via the bitmap fields. For this to work on big endian
platforms, we also need a big-endian represenation of perf_mem_data_src.
