Make strings a first-class token type; defer evaluation

Make strings a proper, first-class token type, instead of relying on
the "TOKEN_NUM with tv_charptr" hack.  Only convert a string to a
number if requested in an expression context; this also makes it
possible to actually issue a warning when it overflows.
