* gc.c: change deafult value of
RUBY_GC_HEAP_FREE_SLOTS_MIN_RATIO 0.3 -> 0.2
RUBY_GC_HEAP_FREE_SLOTS_MAX_RATIO 0.8 -> 0.65
These values are same as Ruby 2.0.0.
This change cause GC counts.
However, generational GC reduced each (minor) GC time and
increase memory locality. So that not so big impact on my
benchmarking results.
(surprizingly, this fix speed up programs on some cases)
You can change these values by environment variables
if you feel wrong.
