This CL adds a quickfix CodeAction that detects "missing method"
compiler errors and suggests adding method stubs to the concrete
type that would implement the interface. There are many ways that
a user might indicate a concrete type is meant to be used as an interface.
This PR detects two types of those errors: variable declaration and function returns.
For variable declarations, things like the following should be detected:
1. var _ SomeInterface = SomeType{}
2. var _ = SomeInterface(SomeType{})
3. var _ SomeInterface = (*SomeType)(nil)
For function returns, the following example is the primary detection:
func newIface() SomeInterface {
return &SomeType{}
}
More detections can be added in the future of course.
Fixes golang/go#37537
