[AArch64] Use neon_<ldm,stm>_2 where appropriate as "type".

Hi,

The final (!!!) patch in the series making types equivalent between
AArch64 and ARM backends deals with insns in the AArch64 backend
which generate ldp and stp. We could invent a new type for these and
add that type to all the pipeline descriptions, but I think the types
neon_ldm_2 and neon_stm_2 describe them adequately.

Tested on aarch64-none-elf with no regressions.

OK?

Thanks,
James

It's close enough.  At least for now.
