ARM64 is 64 bit, we gain nothing by coalescing float immediates as addresses are 64-bit.

Related to issue #10108 and issue #10112.
Replaces 4ad/go#49.

I think loading double precision through indirection is fine, we just have to stop using the pool. I'd really like to get rid of the pool.

For single precision MOVZ+FMOV seems best.
