CRef utilizing an operator syntax can resolve against a regular method with matching special name

[AlekseyTs]

Note that the opposite (resolving a named reference against an operator) can happen as well. Need to confirm whether this is a desired behavior or an oversite.

The following unit tests succeed

            compilation.VerifyDiagnostics();

            int count = 0;
            foreach (var crefSyntax in GetCrefSyntaxes(compilation))

                var actualSymbol = GetReferencedSymbol(crefSyntax, compilation);
                AssertEx.Equal("C1." + (op == "++" ? WellKnownMemberNames.IncrementOperatorName : WellKnownMemberNames.DecrementOperatorName) + @"()", actualSymbol.ToDisplayString());
                count++;
            }

            Assert.Equal(2, count);
        }
