use it.
This also removes "operand" from the affine expr classes: it is unnecessary
verbosity and "operand" will mean something very specific for SSA stuff (we
will have an Operand type).

- check for non-affine expressions
- handle negative numbers and negation of id's, expressions
- functions to check if a map is pure affine or semi-affine
- simplify/clean up affine map parsing code
- report more errors messages, more accurate error messages
