Doug Gregor ceaa5e00bf Suggest explicit protocol conformance via Fix-Its. ...

When we notice that a type implicitly conforms to a protocol but is
not explicitly stated to do so, note this and provide a Fix-It
attaching the conformance to a declaration within the translation
unit, e.g.,

t.swift:28:16: error: type 'S1' does not explicitly conform to protocol 'P'
var p1 : P = S1()
               ^
t.swift:8:8: note: introduce explicit conformance to protocol 'P'
struct S1 : Q {
       ^
             , P
