Example:
# example.rb
p(2e308)
p(-2e308)
Good:
$ bin/mruby example.rb
inf
-inf
Bad:
$ bin/mrbc example.rb
$ bin/mruby -b example.mrb
0
-0
Cause:
Float infinity representation is `inf` on dump and it is converted by
corresponding `String#to_f` on load.
Treatment:
- Introduce new representations (`i`: +infinity, `I`: -infinity)
- Allow old representations (`inf`, `-inf`, `infinity`, `-infinity`) too
- Raise error for unknown representations (use corresponding `Kernel#Float`)
