[PATCH] gimple-ssa-sprintf: Use [0, 1] range for %lc with (wint_t) 0 argument [PR114876]

Hi! Seems when Martin S. implemented this, he coded there strict reading of the standard, which said that %lc with (wint_t) 0 argument is handled as wchar_t[2] temp = { arg, 0 }; %ls with temp arg and so shouldn't print any values. But, most of the libc implementations actually handled that case
