compile.c: store IDs as Symbols

  • compile.c (iseq_set_arguments): store local variable IDs in
    temporary list as Symbols. previously these are stored as
    Fixnums to prevent from GC, but IDs of dynamic symbols can
    exceed Fixnum range and cause RangeError at inverting from
    Fixnum. [ruby-dev:48564] [Bug #10266]
