Update test suite.

	* PrimIO ==> IO
	* change to type of _ccall_

	* update the stdout/stderr files where necessary.

	* make module names consistent: should_compile modules are called
	  ShouldSucceed (don't know why, most of them were already),
	  should_fail modules are called ShouldFail, and should_run
	  modules are called Main (for obvious reasons).
	  Not all done yet.

	* Some tests had bitrot.  Especially some should_fail tests
	  were failing for different reasons than they were originally
	  intended to.
