[PATCH] D145173: Make section attribute and -ffunction-sections play nicely

There are use cases that GC semantics are desired. They may place the address function in a variable.
I don't think changing the behavior by default is fine. Using an option may be fine, but it'd be nicer that GCC commits to do this as well.
