Some targets (e.g. PPC and Hexagon) already did this. I think it's best to do this consistently so that frontend authors don't run into inconsistent results when they emit `naked` functions. For example, in Zig, we had to change our emit code to also set `frame-pointer=none` to get reliable results across targets. Note: I don't have commit access.
