Playground uses run() to automatically sync w compiler passes

Changes playground to use the modified `run()` function of the compiler, polling 
the generator and building up a Map of tabs automatically based on the passes 
that the compiler runs. This means tabs are always derived from the current 
state of the compiler and we can never forget to add a pass.

Note the inclusion of some recently added passes that weren't added to the 
playground — which was my fault but only bc i intended to ship this PR soon :-)
