Add (explicit) AST support for implicit casts. This should simplify the

code generator. Source translation tools can simply ignore this node.

- Added a new Expr node, ImplicitCastExpr.
- Changed UsualUnaryConversions/UsualArithmeticConversions to take references 
to Expr *'s. This will allow these routines to instantiate the new AST node
and pass it back.
- Changed all clients of UsualUnary/UsualArithmetic (lot's of diff's).
- Changed some names in CheckConditionalOperands. Several variables where
only distinguished by their case (e.g. Cond, cond). Yuck (what was I thinking).
- Removed an old/crufty constructor in CastExpr (cleanup).

This check-in does not actually create the new AST node. I wanted to separate
the mechanical changes from the semantic changes. In addition, I need to 
coordinate with Chris, since the semantic change will break the code generator.
