Don't wait to test that all base ptr matches have succeeded

If we successfully cast only the first base node as GlobalAddressSDNode / ConstantPoolSDNode / FrameIndexSDNode then we can early out as we know that base won't cast as a later type.

Noticed while investigating profiles for potential compile time improvements.
