Subject: [PATCH 03/18] Provide way for ui tests to opt out of having their
 output checked.

Namely, this adds support for:

 * `// dont-check-compiler-stdout`, and
 * `// dont-check-compiler-stderr`.

Obviously almost all ui tests wont want to opt into these, since the whole point
of a ui test is to check the compiler ui. However, since this PR is converting
run-pass into (another set of) ui tests, these header options make sense in that
context.

(Also this puts us into a better position for eventually turning
*every* test suite into a ui test suite, by making ui-ness the default
and forcing tests to opt out explicitly.)

Subject: [PATCH 13/18] Add `Rustc` prefixes to `derive(Decodable, Encodable)`.

As a bit of a hack, make `rustc_serialize` an alias of the private
`serialize` crate, just so the new derive continues working.

Fix #54287.

Subject: [PATCH 14/18] Added expected (compile-time) outputs.

* In the case of `derive-same-struct`, it seemed cleaner to add the
  output than to try to modify the macro itself (which is where the
  output is coming from).

* In the case of `custom-derive-partial-eq`, it was just easier to add
  the output than to attempt to port the test to use a procedural
  macro.
