Leonard Chan 7add582032 [Sema] Fix for crash on conditional operation with address_space pointer
Compiling the following causes clang to crash

```
char *cmp(__attribute__((address_space(1))) char *x, __attribute__((address_space(2))) char *y) {
  return x < y ? x : y;
}
```

with the message: "wrong cast for pointers in different address
spaces(must be an address space cast)!"

This is because during IR emission, the source and dest type for a
bitcast should not have differing address spaces.

This fix prints an error since the code shouldn't compile in the first place.

//===----------------------------------------------------------------------===//
// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
