refactor syntax error

Browse source 
* compile.c (append_compile_error): use rb_syntax_error_append.
* error.c (rb_syntax_error_append): append messages into a
  SyntaxError exception instance.
* parse.y (yycompile0): make new SyntaxError instance in main
  mode, otherwize error_buffer should be a SyntaxError if error
  has occurred.
