Otherwise optimizations done in klee won't have any effect.

Shifting negative values is implementation-defined.
Shifting by equal number of the bits as is the size of the type is
undefined.
So fix both of these.
This fixes #911.

also test a negative constant as the lhs.

parallel.
- It would be nice if there was an easier way to do this that didn't involve
editing all of the tests (like running each test in its own directory), but
this approach fixes #146 and doesn't involve changing 'lit' or writing a
wrapper harness. My assumption is a lot of tests start are derived from
another one, so hopefully following this convention won't be burdensome, and
I updated 'make check' so that it will produce an error if any test runs klee
without --output-dir (by checking for the existing of klee-last files).
- This also helps with #147 but I still can't fully run tests in parallel (I
start hitting STP errors).

behaviour for arithmetic right shift are identical.
