Upstreamed Linux kernel has added orig_a0 into struct user_pt_regs.
Adapt GDB register definition so it will work with upstream kernel.

Hi Ruoyao,
Thank you for your patch.
The related code in gdb/loongarch-linux-nat.c also need to be modified.
Additionally, we know that the LoongArch upstream Linux kernel can not
actually be used before efistub, irqchip and pci are merged [0].
[0]
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c6f2f3e2c80e
So I think we can modify the patch subject and the commit message like this:
gdb: LoongArch: Add orig_a0 to match upstream Linux kernel
The basic support for LoongArch has been merged into the upstream Linux
kernel since 5.19-rc1 on June 5, 2022, this commit adds orig_a0 which
is added into struct user_pt_regs [1] to match the upstream kernel, and
then the upstream GDB will work with the upstream kernel.
Note that there is no orig_a0 in struct user_pt_regs in the product kernel
which version is 4.19, if somebody wants to use the upstream GDB with the
product kernel, please revert this commit manually.

Patch v2 follows here:
-- >8 --
The basic support for LoongArch has been merged into the upstream Linux
kernel since 5.19-rc1 on June 5, 2022. This commit adds orig_a0 which
is added into struct user_pt_regs [1] to match the upstream kernel, and
then the upstream GDB will work with the upstream kernel.
Note that orig_a0 was added into struct user_pt_regs in the development
cycle for merging LoongArch port into the upstream Linux kernel, so
earlier kernels (notably, the product kernel with version 4.19 used in
distros like UOS and Loongnix) don't have it. Inspect
arch/loongarch/include/uapi/asm/ptrace.h in the kernel tree to make sure.
To build upstream GDB for a kernel lacking orig_a0, it's necessary to
revert this commit locally.
