yacc.c: use casts instead of pragmas when losing integer width
For instance with Clang 4, 8, etc.:
input.c:1166:12: error: implicit conversion loses integer precision: 'int' to 'yy_state_num' (aka 'signed char') [-Werror,-Wconversion]
*yyssp = yystate;
~ ^~~~~~~
And GCC 8:
input.c:1166:12: error: implicit conversion loses integer precision: 'int' to 'yy_state_num' (aka 'signed char') [-Werror,-Wimplicit-int-conversion]
*yyssp = yystate;
~ ^~~~~~~
* data/skeletons/yacc.c (YY_CONVERT_INT_BEGIN): Remove.
Adjust callers.
