* data/bison.simple (yyr1): Don't use yy_token_number_type as element

* data/bison.simple (yyr1): Don't use yy_token_number_type as element
type; it isn't always big enough, since it doesn't necessarily
include non-terminals.
(yytranslate): Expand definition of yy_token_number_type, so that
the latter can be removed.
(yy_token_number_type): Remove, only one use.
* data/bison.c++ (r1_): Parallel change to yyr1 in bison.simple---
don't use TokenNumberType as element type.

* tests/regression.at: Modify expected output to agree with change
to yyr1 and yytranslate.
