[TableGen] Remove an unnecessary outer 'if' around 3 separate inner ifs. No functiona...

The outer if had 3 separate conditions ORed together and then the inner ifs detected which of the three conditions it was by using only a portion of the specific condition. Just put the whole condition in each inner if and remove the outer if.
