Split the test classes/bradc/arrayInClass/genericArrayInClass-otharrs into a test and a future.

The test shows the ability to create and iterate over arrays-of-arrays that are stored in
classes (which is a valuable test by itself).

The future is due to a bug in zippered iterator inlining, which makes the test fail unless
inlining is turned off.

So, iterator inlining is turned off in the .compopts file associated with the main test.
Details of the bug are provided in the .bad and .future files in the added future test.

Adding the cwd function. This function returns the current working
directory of any running chapel program.
This change removes some stale behavior

The old version of the _defaultOf function for default-sized reals and imags
wanted a cast, because it was specifying the default size rather than just using
it automatically.  With that change, the cast is unnecessary.

io: add chdir [merging for fsouza]

Adding the chdir function, that will change the current directory of any
running chapel program.

This includes two tests: one that tries to chdir to a directory that doesn't
exist, and other that calls chdir, and then writes a file to the current
directory (a new one).
