?miri command

[kangalio]

This command would work similarly to ?eval (or maybe ?play?), but it instructs the Rust Playground to run the code through Miri instead of compiling and executing normally.

The idea came up here: https://discord.com/channels/273534239310479360/274215136414400513/797898675510181901

+1 to this. As a resident of the #black-magic channel on the Rust Community Discord, having the ability to quickly check code that seems to probably be UB or not UB would be rather helpful.
