bhyve needs instruction emul tests
100%
Description
As more unit tests are written as part of the system/bhyve/tests package, it would be nice to have some for the in-kernel instruction emulation. It should be relatively straightforward to create a simple guest environment with a small flat memory space into which isolated instruction tests can be injected and run. The userspace portion of the test could service the as-expected VM exits and check that the desired vCPU states are achieved.

While this was originally desired for testing instruction emulation, the first use case ended up being testing kernel-emulated devices from the perspective of a guest (running an in-guest test payload).
Those tests (timekeeping related) were executed successfully on both AMD and Intel hardware.
