Moot point.

The inliner doesn't really care if the CFG is "correct" or not; it's 
mostly concerned with finding the calls and splicing the blocks.  
Inlining before lowering EH nodes would be easier for the inliner (but 
nobody else seems to be concerned about that ;-).

All those edges are just a nuisance...  :-)

O.K.
