b2eabf4a9f Add tracegen scripts inc. bugfix from @mwachs5 
A step towards moving the tracegen scripts from rocket-chip to
groundtest.  I will raise an issue requesting that the scripts are now
removed from rocket-chip by someone with write access.

I have updated the README to account for the move.

This commit includes a bugfix from @mwachs5 (with slight mods by me)
relating to potential division by zero in toaxe.py.

7285f5e6bf Don't drive D$ kill/phys signals for SimpleHellaCacheIF 
They don't do anything.

51e0870e23 Separate I$ and D$ interface signals that span clock cycles 
For example, Decopuled[HellaCacheReq].bits.kill doesn't make sense,
since it doesn't come the same cycle as ready/valid.

6d3bba6cff Tweaks to README.md 
Remove occurrences of ../scripts/ and instead state that it must be in
your PATH.  Also drop the content introducing the isit script as
tracegen+check.sh subsumes this.
