new clang plugin: loopvartoosmall

Idea from bubli - look for loops where the index variable is of such
size that it cannot cover the range revealed by examining the length
part of the condition.

So far, I have only run the plugin up till the VCL module.

Also the plugin deliberately excludes anything more complicated than a
straightforward incrementing for loop.
