This patch is generated backwards.

I committed the following.  Thanks!

Subject: [PATCH] rs6000: Make an "if" statement more regular

As Akari noticed, we have an unusual "if" statement without parentheses
around the condition.  The condition is a macro that expands to
something with parentheses in the right spot, but, let's make the code a
little less surprising :-)

	* config/rs6000/rs6000.cc (get_memref_parts): Regularize some code.

Hi, Segher!

I'd like to thank you from the bottom of my heart !
I was happy to see my name listed in the github repository as well.

This will motivate me to do my best to commit more to GCC.. :)
