Charlie Turner 424da54881 [InstCombine] Recognize another bswap idiom. 
Summary:
The byte-swap recognizer can now notice that this

```
uint32_t bswap(uint32_t x)
{
  x = (x & 0x0000FFFF) << 16 | (x & 0xFFFF0000) >> 16;
  x = (x & 0x00FF00FF) << 8 | (x & 0xFF00FF00) >> 8;
  return x;
}
```
    
is a bswap. Fixes PR23863.

the license agreement found in LICENSE.txt.

Please see the documentation provided in docs/ for further
assistance with LLVM, and in particular docs/GettingStarted.rst for getting
started with LLVM and docs/README.txt for an overview of LLVM's
