Changeset:

Log:
Fix use of arithmetic with single-character constants in data declarations.
Multi-character constants are still not valid, as they are somewhat
difficult to handle without adding some sort of string handling into
yasm_expr.  This fix may break big-endian targets (we don't have any yet).

* nasm-bison.y: Add new token ONECHARSTR.  Add string rule that takes
STRING and ONECHARSTR; use this instead of STRING everywhere but dataval.
In dvexpr, take ONECHARSTR as character constant.
* nasm-token.re: Generate ONECHARSTR for one-character string contants.
