JDK-8331150 - RISC-V: Fix "bad AD file" bug
Description
Both subword gather load and scatter store are not supported for riscv vector extension.
https://bugs.openjdk.org/browse/JDK-8331150 makes this constraint explicit for subword gather load.
To be safer and more consistent, consider making that explicit for subword scatter store as well.
