crashed when lowering memcpy through MLIR

[PikachuHyA]

test case from clang/test/CIR/CodeGen/libc.c

void *memcpy(void *, const void *, unsigned long);
void testMemcpy(void *src, const void *dst, unsigned long size) {
  memcpy(dst, src, size);
 }

test with clang -c libc.c -fclangir -Xclang -emit-mlir -o libc.mlir -fno-clangir-direct-lowering

test2.c:3:10: warning: passing 'const void *' to parameter of type 'void *' discards qualifiers [-Wincompatible-pointer-types-discards-qualifiers]
