This patch change DependencyAnalysis::SortGlobals() to make sure that
'enable' directive nodes go before any other global declarations in the
sorted global node list, and thus ensure that all extensions will be
registered by reslover before dealing with any other global declarations.
This is necessary because some transforms will add AST nodes before any
other global nodes, and these added nodes should be handled by resolver
after 'enable' nodes are handled.
