On RISC-V we don`t have a node for VectorizedMismatch, and when -XX:+UseVectorizedMismatchIntrinsic option set we got a fatal error caused by: <a href="https://github.com/openjdk/jdk/blob/29ff1e45b910c07711c4f4c3d821712dd9a1e3ba/src/hotspot/cpu/riscv/c1_LIRGenerator_riscv.cpp#L803-L805">https://github.com/openjdk/jdk/blob/29ff1e45b910c07711c4f4c3d821712dd9a1e3ba/src/hotspot/cpu/riscv/c1_LIRGenerator_riscv.cpp#L803-L805</a>.
On other architectures where we don`t have such intrinsic we got only warning. Also, on RISC-V for unimplemented intrinsics like _updateCRC32, _updateCRC32C when we turn on UseCRC32Intrinsics option only warning produced on output.
