Alexandros Lamprineas b4417075dc [FuncSpec] Constant propagate multiple arguments for recursive functions. ...

This fixes a TODO in constantArgPropagation() to make it feature complete.
However, I do find myself in agreement with the review comments in
https://reviews.llvm.org/D106426. I don't think we should pursue
specializing such recursive functions as the code size increase becomes
linear to 'max-iters'. Compiling the modified test just with -O3 (no
function specialization) generates the same code.
