e18759642f Avoid running Chisel in parallel in the same directory 
It looks like Chisel fails when I try to run it in parallel.  This adds a lock
file to ensure that only a single Chisel instance is running at a time when
running the regressions.

c9a2b7d109 Add torture as part of the regression 
Since the latest Spike fix my torture runs are succeeding, so I can now run it
as part of the regression flow.

e185fe6850 Add targets for emulator and fsim regressions 
This change allows the other simulation targets (the emulator and the FPGA
simulator) to be run just like the Verilog simulator could be before.

Support make-3.82 and newer

1149a412cc Support make-3.82 and newer 
make changed its priorties for resolving implicit rules, which causes different
behavior when running "make run-bmark-tests".  This patch changes the hex file
rules to ensure they match between the two versions of make.

I've tried this with both make-3.81 and make-4.1, and they both work for me.

7209c13338 Move to a regression Makefile 
In order to have the buildbot support various types of failures it needs
to run different commands.  Rather than modifying the regression script
to have a bunch of arguments I've just gone and made a makefile for
regressions instead.

This doesn't run torture right now because that's broken, but I'll add
support soon.

2f71a3da5a bump up submodule commits to merge commits 
Github's PR system doesn't work so well with submodules, since it always
creates merge commits. We should probably avoid using it in the future.

7ad9deeaee Fix issues with request merging in L2 cache and add regression tests 
In addition to the fix, there are several additions to the
RegressionTest module. The set of regressions is now parameterized and
split into ones for the cache and ones for the broadcast hub.
