Fix for PR7040: Don't try to compute the LLVM type for a function where it isn't possible to compute. This patch is mostly refactoring; the key change is the addition of the code starting with the comment, "Check whether the function has a computable LLVM signature." The solution here is essentially the same as the way the vtable code handles such functions. llvm-svn: 105151 2010-05-30 06:03:20 +00:00			`// RUN: %clang_cc1 %s -emit-llvm-only`
