Bugfixes

• The borrow checker no longer misses moves and borrows of compile-time constant values. Moving a constant non-Copy value twice, matching the same value by value twice, or reading a local while a mut borrow of it is live is now rejected, as it already was for runtime values. Passing an unannotated string literal to a generic own parameter more than once is no longer reported as a move conflict. (#1649)
• A mut self method that uses a StorageMap or StorageBytes field is no longer rejected with a borrow conflict when called on a contract field whose struct has other fields, for example from a recv handler. (#1659)
