* break & continue scopes are made lazily, and merged into as discovered
Drop ContBreak.
Drop ScopeNode.addScope.
Add a simple mergeScopes.
Simplify Region.inProgress; drop from child classes, use in Region.
Add a ConstantNode.XCONTROL shortcut.
* Fix some regressions
* Error on dead code after break/continue
* A more robust dead-def check
* Fix for dead loop-back path
* Fix scope shadowing bug with continue/break
Turn on LAZY phis by default; fix minor golden test results
* Fix a case with both break & continue

Comment for usefullness of true Loops.
Try to distiguish `PhiNode` as the programming construct from `phi` as the mathematically SSA notation.
Flow long lines.
Remove LAZY flag, set as `true`. Fold up true tests.
* minor comment
* #51 Check _breakScope is not null when parsing break or continue to detect use outside of loop
* #51 in parseComparison we need to move the op= version above the op version, since at this time using <= and >= does not work since they are parsed as > and < with a preceeding = which causes an error
* #51 Update main README to link to chapter 8
* Remove useless test
