Can the Instcombine pass increase the number of instructions of a block?

[LLVMdev] Instcombine increases the number of instructions?
Hi Rafael,
> Can the Instcombine pass increase the number of instructions of a block?
while it usually doesn't, in theory it can increase the number of LLVM IR
instructions. I don't recall an example off the top of my head, but the
usual situation is that replacing some instruction I with a pair J, K
results in better code generation. There are a small number of cases like
this.
