rb_parser_compile_*: remove volatile arg

RB_GC_GUARD is sufficient to prevent tail call optimization from
making the object invisible from GC., and we don't need to
encourage more volatile usage.

* parse.y (rb_parser_compile_cstr): remove volatile arg
  (rb_parser_compile_string): ditto
  (rb_parser_compile_file): ditto
  (rb_parser_compile_string_path): ditto
  (rb_parser_compile_file_path): ditto
  [ruby-core:70323] [Misc #11431]
