LGTM!

The generic code will split 16-byte copy into two 8-byte copies, so the
vector code wouldn't be used even if -mno-strict-align.  This
contradicted with the purpose of this test case.

gcc/testsuite/ChangeLog:

* gcc.target/loongarch/memcpy-vec-3.c: Increase the amount of
copied bytes to 32.

[PATCH] LoongArch: Fix up memcpy-vec-3.c test case

[Xi Ruoyao via Gcc-patches]

The generic code will split 16-byte copy into two 8-byte copies, so the
vector code wouldn't be used even if -mno-strict-align.  This
contradicted with the purpose of this test case.

copied bytes to 32.
