Log:
mn10300: Cleanup all arithmetic.

For addition and logicals, define an operation-plus-flags update pattern
in preparation for compare elimination.  In addition, clean up the way
we compare and validate CC_MODEs.  Define NEG in terms of NOT; this is
smaller and allows a non-clobbering destination alternative.
