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.
