This broke Clang self-host, so I've reverted it in r95430. The failure was:

Assertion failed: ((VTy->isFirstClassType() || VTy->isVoidTy() || isa<OpaqueType>(ty)) && "Cannot create non-first-class values except for constants!"), function Value, file /Users/dgregor/Projects/llvm/lib/VMCore/Value.cpp, line 53.
