Improve the default parallel GC settings, and sanitise the flags (#3340)
Flags (from +RTS -?):
-qg[<n>] Use parallel GC only for generations >= <n>
(default: 0, -qg alone turns off parallel GC)
-qb[<n>] Use load-balancing in the parallel GC only for generations >= <n>
(default: 1, -qb alone turns off load-balancing)
these are good defaults for most parallel programs. Single-threaded
programs that want to make use of parallel GC will probably want +RTS
-qg1 (this is documented).
I've also updated the docs.
