[AARCH64] Split movtf_aarch64 pattern


Hi,

The attached patch is part of the ongoing work to enhance instruction
scheduling opportunities in AArch64.

This patch splits a few alternatives of the movtf_aarch64 pattern, which
used to issue 2 consecutive instructions.
Tested successfully with a full aarch64-elf regression run.

OK for trunk?

Thanks
Sofiane
