Fix PR18800. llvm intrinsic memcpy takes 5 arguments void @llvm.memcpy.p0i8.p0i8.i32(i8* <dest>, i8* <src>, i32 <len>, i32 <align>, i1 <isvolatile>).The test case incorrectly uses the old format resulting in isVolatile function in MemIntrinsic to crash during SROA transformation.Modified the test case to use correct signature of memcpy and memset.
