Reduced test case

Running `opt ~/sccpass-crash.ll  -argpromotion -loop-extract-single -o
/dev/null` results in an assertion failure in CallGraphSCCPass. I've tested
this as of r109867 in a Release+Debug+Asserts build.

Assertion failed: (CallSites.empty() && "Dangling pointers found in call sites
map"), function RefreshCallGraph, file
/Users/collinwinter/src/llvm/trunk/lib/Analysis/IPA/CallGraphSCCPass.cpp, line
333.
