Relooper, Stackifier, decompiler problems

3

Thank you for bringing the Relooper problem class to my attention (and indirectly the [Stackifier](https://medium.com/leaningtech/solving-the-structured-control-flow-problem-once-and-for-all-5123117b1ee2) problem class). . I had previously assumed that bytecode was "always" a 100% decompilable substitute...

Add support for compiling against Emglken

Adjacent branch instructions could be combined before identifying basic blocks, to simply the output and improve performance. However I'm not sure if Inform actually compiles many adjacent branch instructions?

The most common Glk functions (those in `perform_glk`) could be directly output. Match on the function ID and number of arguments so that wrong argument number calls will fall through...

Add more specific reasons to the FunctionSafety enum, and add an option to output a file list each function and its safety status.

Optimisation: if a loop has no next edge pull one non-scc node out

Currently nodes that are not part of a loop scc are not pulled out (ie, made a next edge) unless they are not dominated by the loop header. This means...

Optimise stack operands. Easy to do within a basic block, but across block boundaries would probably require some sort of phi function?
