This is the extension for "Address-Independent Latency of User-Mode Faults to Supervisor Addresses". Spec: riscv/riscv-isa-manual#1564 The spec states that the `svukte` depends on `sv39`, but we don't have `sv39` yet, so I didn't add it to the implied list.

This is the extension for "Address-Independent Latency of User-Mode
Faults to Supervisor Addresses".
Spec: riscv/riscv-isa-manual#1564, https://lf-riscv.atlassian.net/browse/RVS-2977
The spec states that the
svuktedepends onsv39, but we don't havesv39yet, so I didn't add it to the implied list.
