SVE defines an assembly alias:
MOV pa.B, pb/Z, pc.B -> AND pa.B. pb/Z, pc.B, pc.B
Our and<mode>3 pattern was instead using the functionally-equivalent:
AND pa.B. pb/Z, pb.B, pc.B
^^^^
This patch duplicates pc.B instead so that the alias can be seen
in disassembly.
I wondered about using the alias in the pattern instead, but using AND
explicitly seems to fit better with the pattern name and surrounding code.

* config/aarch64/aarch64-sve.md (and<PRED_ALL:mode>3): Make the
operand order match the MOV /Z alias.
