Prior to this patch, debug info was storing the original swift type for function objects. This could be very wrong in optimized code. This patch stores the lowered function type in the debug info and adds the necessary type reconstruction code (tested via the LLDB testsuite) to allow reconstructing a Swift type from a mangled lowered type. <rdar://problem/28859432>
