[PATCH v2 0/5] gas: aarch64: Add support for GICv5 extension

[saurabh.jha@arm.com]

From: Saurabh Jha <saurabh.jha@arm.com>

V2 of this patch series:
https://sourceware.org/pipermail/binutils/2025-September/143918.html

Thank you for the review! Addressed comments, and in particular,
1. In the first patch, added the acronym for gcie rather than gic.
2. In the second patch, used xzr in tests and now only testing with x0
and xzr. The other tests were redundant and were not as readable.
3. In the second patch, encoded Rt as 0b11111 in the gsb instruction as
specified by the spec.
4. In third, fourth, and fifth patches, edited the commit title to make
it more understandable.
5. In third, fourth, and fifth patches, dropped 'sys_reg=' in tests.
Also removed F_ARCHEXT in aarch64-sys-regs.def.

I am planning to commit this in about 24 hours unless anyone has any
objections.

Many thanks,
Saurabh
