[PATCH] AArch64: Implement big endian bit-conversion for NEON types

[Christian Pirker]

Hi James,

the patch implements and tests both 64 and 128 vector-to-scalar (and vice versa).
I don't see any meaningful usage of vector-to-vector conversion using rev instructions.
Would you be able to provide a use case?

Thanks,
Christian
