Repro

It seems MDNode::get() doesn't handle the parameters of a Function correctly in
case when the parameters were added to the ParameterList after the Function was
created. I attach a repro (trunk). It contains 2 cases: 1st where it fails to
include the parameters, 2nd where it works. Only difference of both is that in
the fist case the parameter was added later whereas in the 2nd case it was
given at Function creation time. It should output the same metadata in both
cases, right?
