This removes a gratuitous ifdef on TARGET_UNWIND_INFO.

Putting the data before assemble_end_function is required for
the various targets that actually define TARGET_UNWIND_INFO;
putting the data after assemble_end_function doesn't really
matter for dwarf2/sjlj exceptions.

I plan to entirely remove the TARGET_UNWIND_INFO macro, and
this is one step.

Tested on x86_64-w64-mingw32 (with other patches), crosses to
ia64 and arm-eabi, and a sanity check on x86_64-linux.
