where "live debug bind reset of dead var" means the variable is unused
but there were debug binds with a value for them and
"dead debug bind reset" means the variable is unused and there were
only debug bind resets (each reset of the same variable is counted
for both counters). This shows A considerable amount of dead stmts

added support for these. The name of vec_clzm became vec_cntlzm,
and vec_ctzm became vec_cnttzm. Four of the overloaded forms of

unsigned int, not an unsigned char. This patch reflects those
