This is currently a Draft and not ready for review.

PR #91779 implemented initial support for RFC 3191 which caused a noticeable perf regression tracked by #96786. Implementing a few different changes to drive down the perf regression such as only querying for the #[debugger_visualizer] attribute when targeting msvc.

@rustbot rustbot added the T-compiler Relevant to the compiler team, which will review and decide on the PR/issue. label May 6, 2022
