Hi,

I published loongarch64 port v5 in
https://github.com/loongson/musl/tree/loongarch-v2.0.

fixed the following problems:
1.Removed arch/loongarch64/bits/hwcap.h,which is not used.
2.Removed the unused macro definitions in arch/loongarch64/bits/reg.h.
3.#define SA_RESTORER 0x0,which means invalid in LoongArch.
4.Modified the position of "loongarch64*) ARCH=loongarch64 ;;" by 
Alphabetic order in configure.
5.Modified the macro definition of VDSO_CGT_VER to "LINUX_5.10"
6.Modified the macro definition of EF_LARCH_ABI and EF_LARCH_ABI_LP64D 
in elf.h
7.Modified some inappropriate comment.
8.Some assembly instructions optimization.

please check again,I'm Looking forward to your reply,thanks.

Hongliang Wang.
