The DCache input for invalidating LR reservations was dangling. Now
we wire it to false.

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.

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.

Updates to the trace-generator: (1) Don't terminate via HTIF exit, which can cause other, unfinished, cores to be cut short. Instead emit FINISHED messsages allowing an external process to send a SIGTERM to the emulator once all cores have finished. (2) Add some support for greater address variation without having to recompile, disabled by default. (3) Generate atomic, LR/SC, and fence operations by default in addition to plain loads and stores. These changes require newer versions of files in the rocket-chip/scripts directory. I will submit a pull request for those too.
