8e5166bb2e Move the constant folding code to lslfoldconst.py.
lsloptimizer remains as the "conductor" and option handler.

As a result, new options have been added to enable DCR and constant folding.

beea757a0a Fork (add a copy of) lsloptimizer.py as lslfoldconst.py.
This commit is just a copy, to hopefully help git track it. The changes come in the next commit.

This is preparation work for splitting the optimizer.

9c4d81db08 Implement side-effect-free (SEF) analysis. Also optimize x++ to ++x.
As an additional bonus, the condition folding function is now the one that converts a condition to -1, relieving that burden from the rest of the code and simplifying tests.

24a32c30e3 Fix bug where folding a FOR loop with const false cond produced bad code.
More precisely, the initializator list was not wrapped into EXPR nodes. Now it is.

While on it, fix a minor bug (the substitutive of a FOR statement should produce no output type), and change order of execution to the actual one (iterators come last).

17e94a0d0f Add FoldCond as a stub. Change cond constant to -1. Add support for EXPR.

67f3061e19 Fix state switch error reporting bug. Add 'Not all code paths...' error.
Add corresponding tests too. Simplify the identifier renaming coverage test. Also remove extra newlines from library reading code.

We've had to give up on the 'else if' loop-instead-of-recurse optimization, to properly propagate the LastWasReturn flag.

14e5b78d94 Remove empty statements. Optimize out 'else ;' and 'else {}'.
Without empty statement removal, {;} would trick the optimizer into believing the statement was not empty. E.g. if(x) ; else {;} would not remove the else.

d65f0f1f75 Fully implement duplabels, and prepare output for general renaming.
There's also a new hidden option, shrinknames, which automatically enables duplabels due to its nature. The idea is that once general renaming is implemented, in order for label names to not cause collision trouble, they are renamed out of the way with unique names.

Not entirely sure this is really necessary.

e29f16d3eb Add duplabels option (not yet implemented).
When disabled, it now disallows duplicate labels. The plan is that when enabled, it will auto-rename labels so that there are no repetitions within a function.

Add coverage tests too, and also a coverage test that was missed after the latest changes.
