given a something, determine if it is a Name

 Return a Name, and a possible rest that has a hoisted part of the statement

 eg  if( @var % 5) is not normalized
 but if(tmp_123) is with tmp_123 = @var % 5 hoisted above the if

 also constants count, though they may not be so useful in ifs, but returns
