Make classes final, and add some attributes to methods definitions to speed up slightly

[Temtaime]

???

[tchaloupka]

Just an indentation caused by:

• @safe pure
• {

removed unneeded new because BasicBlockEdge is a struct

oh, so many hacks, i dont like hacks, which make bad code readability, d not changed, ldc used 25s
also gdc fails to compile: havlak.d:35: error: safe function 'havlak.CFG.createNode' cannot call system function 'object.AssociativeArray!(int, BasicBlock).AssociativeArray.get' havlak.d:47: error: safe function 'havlak.CFG.getNumNodes' cannot call system function 'object.AssociativeArray!(int, BasicBlock).AssociativeArray.length'

So what about this?
Just added module level final to make all classes final (unfortunately not set as default in D), which has a "major" impact for results over the rest previously used attributes as @safe, pure, etc.
Replaced printf with writeln (no perf hit)
Changed constants to enums (no perf hit)
Removed new from struct initialization - not needed.

thanks, but what this final means?

[tchaloupka]

It means that final classes cannot be subclassed. In D all methods of class are virtual by default and being so means some ovehead calling them.
I dont understand this decision, but it is how it is ;-)
