Reviewed by Justin Michaud.

This patch enhances the ARM64 disassembler to correctly handle and display
additional SIMD instructions, particularly those involving different vector
element sizes (.B, .H, .S, .D). This improvement allows for more accurate
representation of ARM SIMD instructions in the disassembled output.
