Hi,
movtf is unnecessary as a separate expander. Move this to be with
the standard scalar floating point expanders.
Achieved by adding a new iterator and then using the same.
Tested cross aarch64-none-elf and no regressions.

* config/aarch64/aarch.md (mov<mode>:GPF): Use ALLTF.
(movtf): Delete.
* config/aarch64/iterators.md (ALLTF): New.
