Re:[pushed] [PATCH] LoongArch: Make __builtin_lsx_vorn_v and __builtin_lasx_xvorn_v arguments and return values unsigned

[Lulu Cheng]

Pushed to r15-5580.

We searched in the multimedia package and found no cases of using 
__builtin_lsx_vorn_v or __builtin_lasx_xvorn_v,

so the interface type has been modified in the form of a bugfix.

Thanks!

Align them with other vector bitwise builtins.

This may break programs directly invoking __builtin_lsx_vorn_v or
__builtin_lasx_xvorn_v, but doing so is not supported (as builtins are
not documented, only intrinsics are documented and users should use them
instead).

gcc/ChangeLog:

        * config/loongarch/loongarch-builtins.cc (vorn_v, xvorn_v): Use
        unsigned vector modes.
        * config/loongarch/lsxintrin.h (__lsx_vorn_v): Cast arguments to
        v16u8.
        * config/loongarch/lasxintrin.h (__lasx_xvorn_v): Cast arguments
        to v32u8.

gcc/testsuite/ChangeLog:

        * gcc.target/loongarch/vector/lsx/lsx-builtin.c (__lsx_vorn_v):
        Change arguments and return value to v16u8.
        * gcc.target/loongarch/vector/lasx/lasx-builtin.c
        (__lasx_xvorn_v): Change arguments and return value to v32u8.

Now running bootstrap & regtest.  Posted early as a context for some
LLVM patch.  I'll post the regtest result once it finishes.
