<pre>The attached IR compiles fine with "llc", but triggers an assertion if
optimized before with "opt -O2":
Assertion failed: cast<DISubprogram>(Scope)->describes(MF->getFunction()), file
C:\s\d\ldc\llvm\lib\CodeGen\LexicalScopes.cpp, line 160
Strangely, it doesn't assert with "llc -O2". The same compiles without debug
info.</pre>
