Increase the number of items in a char set from 128 to 256, to cover all

possible bytes (7-bit bytes are so 70s).

Add a test (currently failing) to check that Pascal char sets can store all 256
...
possible values. Add the PowerPC ncg and mcg backend support to let the test
actually run, including modifying a bunch of PowrePC libem functions so that
they can be called from both ncg and mcg.
