Indeed. Having the information in the invoke kinda alleviates this
problem, but removing the invoke syntax will bring that back.

One way to merge two basic blocks is to split into several smaller
basic blocks with same properties and then branch to and from that new
sub-block instead of actually moving the instructions inside the
merged block.

I don't know the effects of block fragmentation in LLVM, but that
would definitely increase it. But having EH info in every instruction
is also too much... :/

cheers,
