Cycle counting for SPIM 7.2.1

We use SPIM for the graduate compiler course at CSU. Francis Hsu provided a copy of Spim 6.5, which had been modified for use with Alex Aiken's COOL project. Their modifications count the number of instructions executed, reads, writes, and branches that occur within a Mips program as it is simulated with SPIM. I applied the same modifications to SPIM 7.2.1.

Example usage

% ./spim -keepstats file.s
