LiveVariableAnalysis didn't have a getDependencies method => the DEPENDENCIES constant was never used and OptimizeDynScopesPass not returned as a dependency:

• Added the getDependencies method
• Made DEPENDENCIES private here and in the parent to make this a little less confusing (other children of CompilerPass use the same approach => private rules out any inheritance weirdness imo :))

Also:

• Removed dead field listeners from CompilerPass
• Made NO_DEPENDENCIES in CompilerPass private since none of the child compiler passes use it (if they don't override getDependencies they get no dependencies => no need to use the constant in children)
