I think there is a counting error here: Each LLBB symbol appears twice
- once before the instruction that starts the block, and once in the
debugging information.

Counting lexical blocks is perhaps also easier with

tr -cd '{' <generate.ii | wc -c

Of course, this probably still gives more blocks than appear in
source. Some are apparently redundant, however, there are also good
reasons for others. For example, I guess inline functions result in
new lexical blocks every time they are inlined.
