This disables BigInteger.multiplyToLen(), BigInteger.squareToLen(), BigInteger.montgomeryMultiply()
and BigInteger.montgomerySquare() on linux-riscv64 platforms where misaligned memory accesses is slow.
The reason is that these four BigInteger intrinsics do 8-byte misaligned memory accesses to int arrays
under -XX:+UseCompactObjectHeaders. And this will have a negative impact on SPECJvm2008 crypto tests.
