Integrate rv32i conformance tests

[eriktai]

I have modified the simulator which is compatible with the riscv-compliance tests procedure.

[jserv]

Again, use git rebase -i to rework the commits. Minimize the changes and ensure fully corresponding to conformance tests as the subject claimed.

Remove compressed instruction related commits in this pull request.

[jserv]

Can you rebase upstream/master again?

[jserv]

Any progress?

Sorry, I finished it but didn't push up. I changed the flow of the conformance test, which was better. No need for the operation of copying any more.

Sorry, It's been a while for not updating this PR. Except I will delete the CSR.h file which is not necessary for this conformance test. My integrity of conformance tests is doing right? After this, I want to output a detailed log file the same as other simulators.

So far, your changes work out-of-box except the inconsistency I mentioned earlier.
