Implement builtins for prototypes:

signed int vec_cntlz_lsbb (vector signed char);
signed int vec_cntlz_lsbb (vector unsigned char);
signed int vec_cnttz_lsbb (vector signed char);
signed int vec_cnttz_lsbb (vector unsigned char);
vector unsigned int vec_parity_lsbb (vector signed int);
vector unsigned int vec_parity_lsbb (vector unsigned int);
vector unsigned int128 vec_parity_lsbb (vector signed int128);
vector unsigned int128 vec_parity_lsbb (vector unsigned int128);
vector unsigned long long vec_parity_lsbb (vector signed long long);
vector unsigned long long vec_parity_lsbb (vector unsigned long long);
