inttostr: simplify by removing unnecessary redundancy * lib/anytostr.c: Don't include verify.h. (anytostr): Don't verify that TYPE_SIGNED (inttype) equals inttype_is_signed. Instead, use TYPE_SIGNED (inttype) directly. This removes the need for inttype_is_signed, which was put in to suppress some GCC warnings about conversions. This rewrite should also suppress those warnings. * lib/imaxtostr.c (inttype_is_signed): Remove; no longer needed. * lib/inttostr.c, lib/offtostr.c, lib/uinttostr.c, lib/umaxtostr.c: Likewise. * modules/inttostr (Depends-on): Remove 'verify'.
