[AArch64][SVE 26/32] Add SVE MUL VL addressing modes
This patch adds support for addresses of the form:
[<base>, #<offset>, MUL VL]
This involves adding a new AARCH64_MOD_MUL_VL modifier, which is
why I split it out from the other addressing modes.
For LD2, LD3 and LD4, the offset must be a multiple of the structure
size, so for LD3 the possible values are 0, 3, 6, .... The patch
therefore extends value_aligned_p to handle non-power-of-2 alignments.
