  Log Message:
  -----------
  Warning for incorrect use of 'pure' attribute (#78200)

This adds a warning when applying the `pure` attribute along with the `const` attribute, or when applying the `pure` attribute to a function with a `void` return type (including constructors and destructors).

Fixes https://github.com/llvm/llvm-project/issues/77482
