* parse.y (parser_initialize): explicitly call rb_ascii8bit_encoding().

Browse source 
* parse.y (parser_prepare): lex_input may not be have encoding (e.g. IO).

* parse.y (rb_parser_compile_string): set encoding from input string. 

* encoding.c (rb_enc_find_index): use ASCII-8BIT if loading known
  encoding failed.
