data: Run sse vs. no-sse tests on edison

These show a 1.81x speedup for SSE, which is annoyingly lower
than the speedup I measured earlier (1.975).  Unfortunately, I
lost the data for that run when I foolishly failed to back up
my Hopper runs.
data: Run sse vs. no-sse tests without hyperthreading

This produces an even worse speedup than with hyperthreading
for some reason.  Maybe I should test on my laptop.
Add operation counts to some of the SSE routines
Run sse vs. no-sse benchmarks on my laptop

These seem to reproduce my original numbers.  I'll report both
these and the Edison numbers in the paper.
bin/analyze: Add total statistics
data/edison: Add more small benchmark runs
mpi/io: Use MPI_File_write_at_all instead of MPI_File_write_ordered
data/edison: Rerun history with fixed sparse I/O
Add final data information as a text file

It's still a tag, but tags are somewhat nondiscoverable.
data/edison/project: Add a 96-thread history run
Draft the paper
