tests/lint: remove .exp files, as they have become redundant

Now that each lint1 test lists all generated diagnostics as 'expect'
comments, the information from the .exp files is no longer needed.  The
only information that gets lost is the order of the diagnostics, which
is mostly relevant for paired messages like 'inconsistent definition' +
'previous definition was here'.

lint: disable check for enum type mismatch in switch statement

This check has been too quick and broke the lint build.  Among others,
lib/libpuffs has -w included in LINTFLAGS, which means that the build
can fail even for new warnings, not only for errors.

libpuffs compares a uint16_t with constants from an unnamed enum type.
Since the enum type is completely unnamed (neither a tag nor a typedef),
there is no way to define a struct member having this type. This was a
scenario that I just didn't consider when I added the check to lint.

For now, disable the new check completely.  The previously existing lint
checks stay enabled, including the one that warns about mismatched
anonymous enum types in the '==' operator, which is very similar to the
now disabled check.

tests/lint: add tests for comparison between unnamed enums

Since unnamed enum types cannot be used in type casts, there is no
sensible way that this type mismatch could be resolved, without changing
the definition of the enum type itself, but that may be in a
non-modifiable header.

Therefore, comparisons with enum constants of unnamed types cannot be
sensibly warned about.

lint: warn about enum/enum or enum/int type mismatch in switch

This is something that neither GCC 10 nor Clang 8 do, even though it
seems useful.  Lint didn't do it up to now, but that was probably an
oversight since it is easy to miss the implicit '==' operator in the
switch statement.

lint: add a test for each message produced by lint1

Having a test for each message ensures that upcoming refactorings don't
break the basic functionality.  Adding the tests will also discover
previously unknown bugs in lint.

The tests ensure that every lint message can actually be triggered, and
they demonstrate how to do so.  Having a separate file for each test
leaves enough space for documenting historical anecdotes, rationale or
edge cases, keeping them away from the source code.

The interesting details of this commit are in Makefile and
t_integration.sh.  All other files are just auto-generated.

When running the tests as part of ATF, they are packed together as a
single test case.  Conceptually, it would have been better to have each
test as a separate test case, but ATF quickly becomes very slow as soon
as a test program defines too many test cases, and 50 is already too
many.  The time complexity is O(n^2), not O(n) as one would expect.
It's the same problem as in tests/usr.bin/make, which has over 300 test
cases as well.
