stats: add option to disable alignment spaces in stats.txt file
The alignment spaces in stats.txt takes up a lot of space and increases
simulation time, this commit adds the option to disable them with:
--stats-file stats.txt?spaces=False
Sample old lines with ?desc=False:
system.cpu.op_class::FloatMultAcc 0 0.00% 65.92%
system.cpu.op_class::FloatDiv 0 0.00% 65.92%
Sample new lines with ?desc=False;spaces=False:
system.cpu.op_class::FloatMultAcc 0 0.00% 65.92%
system.cpu.op_class::FloatDiv 0 0.00% 65.92%
On a 1000 dumpstats m5op loop spaces=False reduces:
* size: from 38MB to 20MB
* time: from 4.5s to 3.5s
