LWG3175 identifies that the `common_reference` requirement for
`swappable_with` is over-constraining and doesn't need to concern itself
with cv- or reference qualifiers.

The "user-defined conversion by implicit constructor" codepath is already
handled by `B(int)`; we don't need to test `A(const A&)` a second time
via `DA` (nor the isomorphic case with `DB`).
We don't need `&` anywhere in this test.
Generally, `operator()` should be const; this test needn't be special.
(No functional change in test coverage.)
This should be clearer, instead of relying on rules for implicit
conversions regarding built in float/integer types.

MSVC had a bug regarding preferring intergral conversions over
floating conversions. This is fixed in MSVC 19.28 and newer. Clang in
MSVC mode so far only mimics the old, buggy behaviour, but will
hopefully soon be fixed to comply with the new behaviour too
(see https://reviews.llvm.org/D99663).
Make the negative test to use a distinctly different type,
leaving checks for compiler specific bugs out of the libcxx test.

C++98 and C++03 are effectively aliases as far as Clang is concerned.
As such, allowing both std=c++98 and std=c++03 as Lit parameters is
just slightly confusing, but provides no value. It's similar to allowing
both std=c++17 and std=c++1z, which we don't do.
This was discovered because we had an internal bot that ran the test
suite under both c++98 AND c++03 -- one of which is redundant.
