Introduce support for C++0x explicit conversion operators (N2437)

Small cleanup in the handling of user-defined conversions. 

Also, implement an optimization when constructing a call. We avoid
recomputing implicit conversion sequences and instead use those
conversion sequences that we computed as part of overload resolution.
