Merge pull request #206 from benharsh/fasta-stdin-perf

Enable performance testing for fasta-dependent shootouts.

Each of these benchmarks takes as input the file generated by the fasta benchmark. They are all given a PREEXEC file that generates the input file sizes needed, and places them in test/tmp. This script will only run during a performance run, and will only generate files if they don't already exist. start_test will attempt to remove the test/tmp folder at the end of its script.
