AArch64: Remove unnecessary temporary variables.
Removes temporary variables in AArch64 opcode decoding, assigning directly to the operand info.
The AArch64 disassembler code had some temporary variables that were assigned to operand info. This commit streamlines the code by directly assigning the computed values to the operand info, removing the need for the temporary variables.
In Details
The AArch64 disassembler in opcodes/aarch64-dis.c contained redundant temporary variables. This commit removes them, assigning directly to info->qualifier.
For Context
When converting machine code back into assembly (disassembling), the binutils need to extract information about each instruction's operands. This commit simplifies the AArch64 disassembler by removing temporary variables used in the process of extracting operand information. This makes the code cleaner without changing the disassembly output.
