Kevin Newton 6cd25700b5 [ruby/prism] Extend state stacks indefinitely ...

An old and very obscure bug resulting from using fixed-size
integers to hold state stacks.

Prism uses u32, and parse.y uses u64. Both of them have problems
if they overflow. Instead, use a growable state stack that can
extend indefinitely so this is never a problem.
