[AArch64][SVE 25/32] Add support for SVE addressing modes

This patch adds most of the new SVE addressing modes and associated
operands.  A follow-on patch adds MUL VL, since handling it separately
makes the changes easier to read.

The patch also introduces a new "operand-dependent data" field to the
operand flags, based closely on the existing one for opcode flags.
For SVE this new field needs only 2 bits, but it could be widened
in future if necessary.
