Deprecated signed integer types (non fixed-width) for bitwise reductions are being tested

[davidozog]

We are testing deprecated types for bitwise reductions (short, int, long, and long long) in the SOS test suite, but these are deprecated and not supported by other libraries (e.g. OSHMPI).

I think we should remove them from the tests and consider marking the routines as deprecated, if possible. Removal might be appropriate too, because the operation is possibly ambiguous (given that these types might have either 1's or 2's complement representation).
