  [Clang] Improve `-Wtautological-overlap-compare` diagnostics flag (#133653)

This PR attempts to improve the diagnostics flag
`-Wtautological-overlap-compare` (#13473). I have added code to warn
about float-point literals and character literals. I have also changed
the warning message for the non-overlapping case to provide a more
correct hint to the user.

Fixes #13473.
