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.

Ramana

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