Log Message:
Avoid unnecessary pattern matching in ?ap? combinators.

In those combinators where the trace component of a wrapped expression is not always needed, pattern matching on `R' is moved to a case expression in the combinator body.

Time measurements are too imprecise to determine if this has any effect on runtime.
