S390: [sim] Add icount and si <mnemonic> commands.

Typing icount at the sim debug prompt will print the current icount.
si <mnemonic> steps through instructions until an instruction with that
mnemonic is seen.
E.g. si brc will stop at the next brc instruction before executing it.

No L-G-T-M from a valid reviewer yet. 
CQ run can only be started by full committers or once the patch has
received an L-G-T-M from a full committer.
Even if an L-G-T-M may have been provided, it was from a non-committer,
_not_ a full super star committer.
Committers are members of the group "project-v8-committers".
Note that this has nothing to do with OWNERS files.
