Jit: Conditional Escape Analysis and Cloning by AndyAyersMS · Pull Request #111473 · dotnet/runtime

@AndyAyersMS 

Enhance escape analysis to determine if an object escapes only under
failed GDV tests. If so, clone to create a path of code so that
the object doesn't escape, and then stack allocate the object.

More details in the included document.

Contributes to dotnet#108913
