Use `' quotes (as in `foo') to differentiate from Go quotes.
Quoting prevents confusion when user-supplied names alter
the meaning of the error message.
For instance, report
duplicate method `wanted'
rather than
duplicate method wanted
Exceptions:
- don't quote _:
`_' is ugly and not necessary
- don't quote after a ":":
undefined name: foo
- don't quote if the name is used correctly in a statement:
goto L jumps over variable declaration
Quoting is done with a helper function and can be centrally adjusted
and fine-tuned as needed.
Adjusted some test cases to explicitly include the quoted names.
Fixes#65790.

Support for overlapping interfaces is a new (proposed) Go language
feature to be supported in Go 1.14, so it shouldn't be supported under
-lang=go1.13 or earlier.
Fixes#34329.
