Check for NULL file descriptors before close()

I have no idea why this is happening, but I get some SEGVs when trying
to run some code under the test harness.  I figured I'd just be
explicit and test for NULL pointers.  This appears to have made the
failures go away, but they were sporadic so who knows.

This was was breaking I/O Vecs, but wasn't a strictly necessary change.
We can revisit naming of ROM inputs later.

Check for NULL file descriptors before close()
Print stdin from Scala tests to a file

This allows me to run some chisel code that uses the Scala test
harness without Scala running.  This is nice because it allows me to
run these tests as part of my automatic test harness, without having
to deal with all the SBT stuff that I don't understand.
Add "--dumpTestInput" as an argument

This will cause the stdin that's read by the tester to get dumped to a
file during every run.  The file will be named "Design.stdin", where
"Design" is the name of the top-level design that's being run (it's
the same as the rest of the generated files, like "Design.cpp" or
"Design.vcd").

I'm currently using this functionality in order to attempt to get
completely determintsic tests so I can run both the C++ backend and my
new LLVM backend and expect to get the same result.

It could be useful for running tests on embedded systems that can't
run Scala (like the Zedboard).
Corrected script to use bash features.
