Log:
[AArch64] Use aarch64_reg_or_imm instead of nonmemory_operand

Some of the shift expanders accepted nonmemory_operands but were only
able to handle register_operands or CONST_INTs.  This is probably
academic without SVE, since we're not likely to see shifts by other
types of constant (const_wide_ints, consts, etc).  But for SVE,
it's possible for a vectorised shift induction to have a CONST_POLY_INT
shift amount.

This patch makes the expanders use aarch64_reg_or_imm instead.
