[AArch64] When printing SYS aliases, use explicit `NeedsReg` flag from tablegen (NFC) (#140484)

Currently, when printing SYS aliases, the first instruction operand is
compared with the string constant "all" to decide if a register needs to
be parsed as the next operand.

For example, `TLBI VMALLE1IS` contains "all" so no register is expected,
but `TLBI IPAS2E1IS` doesn't match, so a register is expected.

Future AArch64 SYS aliases won't always match this pattern, so use the
(already provided) explicit `NeedsReg` bit flag provided in tablegen to
check if a register is required to be parsed. This is already used by
the code in `AArch64InstPrinter.cpp`, so now we are consistent in this
source file too.

No test files have been changed, since this is a non-functional change,
and all AArch64 test cases continue to pass after this change.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.
