Relatively simple task for contributors: making microbe not stay in infinite loop

[Zoltan Padrah]

 Hi,

based on my current testing, microbe (the program that generates
assembly code from flowcode) remains stuck in an infinite loop for
some flowcharts.
Because microbe is quite self-contained, fixing it should be a good
task for new contributors.

Based on my initial investigation, the optimizer inside microbe gets
stuck: it has a loop, in which it tries to further optimized the
code/program as long as it changes something. However, it never
reaches a "final" state of the code/program, and it always finds
something to change, thus remains stuck in an infinite loop. I have
not investigated the issue further.

If anybody feels like looking into this, please write to the list.

Have fun,

 Zoltan
