+Subject: [PATCH 03/29] Loongarch: Add ifunc support and add different versions
+ of strlen
+
+strlen-lasx is implemeted by LASX simd instructions(256bit)
+strlen-lsx is implemeted by LSX simd instructions(128bit)
+strlen-align is implemented by LA basic instructions and never use unaligned memory acess
