* gc.c, parse.y: support generational Symbol relatetd marking.
Each symbols has String objects respectively to represent
Symbols.
These objects are marked only when:
* full marking
* new symbols are added
This hack reduce symbols (related strings) marking time.
For example, on my Linux environment, the following code
"20_000_000.times{''}"
with 40k symbols (similar symbol number on Rails 3.2.14 app,
@jugyo tells me) boosts, from 7.3sec to 4.2sec.
