Do you have to add a subfloor to subfloor of a bathroom before adding backer board?

Not usually, no. As long as the sub floor is solid, without water damage, etc then a backer board is usually plenty.
You need to have 1 1/4" of sub floor and backer board when you put the tile down. Generally speaking, homes are built with at least a 3/4" sub floor and 1/4" cement backer board with 1/4" x 1/4" trowel of thinset equals this.
If you are not sure, don't assume. Find a vent in the floor. Pull out the register vent and use a hand mirror to see the sub floor. Take a tape measure and measure its thickness.

What do you need to put on top of a wooden porch floor before putting porcelain tile on it?
First, make sure it's level and very sturdy. The materials going down add up to a lot of extra weight, so make sure your porch was build to support it. Next, you'll want to lay backer board. I prefer hardi-backer 1/4 inch. There are several other brand that will work as well, but hardi backer is light weight and easier to work with. Make sure to hit all your mounting points with the correct type of screws (backer-on are made for this, but you can just as easily use another). Tape up your seams with backer board tape and your ready for thinset
