bench_compare proper spacing and tab option.

bench_compare proper spacing and tab option.

[bungeman, 2012-12-07 22:37:19]

This CL makes bench_compare executable, makes the spacing always work, and gives
the option of tab delimited output.

These changes were recently helpful while looking at the sorting benches.

can you post a sample before and after output?

Well, it looks the same as it used to if you don't use the new command line
options, except that the columns always line up. Before there were issues with
really long config names causing things to go out of kilter, like
'bitmap_8888_update_volatile_scale_rotate_filter'.

With -t the output looks silly (tab delimited columns), but imports into
spreadsheets well. It also plays nice with other command line tools, so you can
do silly things like 'bench/bench_compare.py -o ../oldbench.txt -n
../newbench.txt -t | grep font | sort -g -k4 | column -t' to show configs with
'font' in the name sorted by old time (numerically) and displayed as a table.

'--match' works the same way '--match' works in other tools, it only outputs
benches that start with the '--match' value.
