Log:
Remove remaining uses of * in patterns
Remove the remaining uses of '*' from aarch64.md.
Using '*' in alternatives is typically incorrect as it tells the register
allocator to ignore those alternatives. Also add a missing '?' so we
prefer a floating point register for same-size int<->fp conversions.
