[PATCH] D141892: Implement modernize-use-constraints

[Chris Cotter via Phabricator via cfe-commits]

ccotter added a comment.

Overall, we could eventually upgrade code in three stages, each a separate reusable check.

1. enable_if -> requires clauses
2. replace the non `_v` templates to the `_v` variants `is_same` -> `is_same_v` or the equivalent concept `same_as`
3. replace requires clause on declarations to be template type constraint (replace `template <typename T> void foo() requires std::same_as<T, int> void foo() {}` to `template <std::same_as<int> T> void foo() {}`
