58d6af207f Cache all the Scala build directories 
I hope this will result in Travis building our stuff a lot faster, since this
currently takes about half the time.

bae4c0c0c9 Point Testing to $RISCV/... not $base_dir/... 
This uses the compiled tests in RISCV, which match the rest of the toolchain.

a073c37e36 The FPGA doesn't have an HTIF clock divider 
We used to just be writing the SCR anyway, but now that the SCR maps are
automatically defined VCS will detect the missing SCR and bail out when
compiling test harness code.  This patch just doesn't write the HTIF SCR when
there isn't one.

926efd0cab Allow the number of memory channels to be picked at runtime 
We're building a chip with 8 memory channels.  Since this will require a
complicated test setup we want to also be able to bring up the chip with fewer
memory channels.  This commit adds a SCR that controls the number of active
memory channels on a chip.  Toggling this SCR will scramble memory and drop
Nasti messages, so it's only possible to change while the chip is booting.

By default this just adds a 1-bit SCR, which essentially no extra logic.

When multiple memory channel configurations are enabled at elaboration time, a
NastiMemoryInterconnect is generated for each channel configuration.  The
number of outstanding misses is increased to coorespond to the maximum number
of banks per memory channel (added as a parameter), which I believe is
necessary to avoid deadlock in the memory system.

A configuration is added that supports 8 memory channels but has only 1 enabled
by default.

db9de94588 Generate and use SCR address header files 
This uses the new SCRFile changes to generate a header file containing a list
of all the SCRs in a core to remove the magic constant "63" (the HTIF clock
divider control register) and replace it with a generated number (which is
still 63).

b2ed35e8aa Print a better error on missing config classes 
Without this you don't actually see what config class you tried to use, which
makes it hard to grep around Makefiles to see why things are broken.

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.
