- Fix cases where we generated horrible code like this: · fac8452a
  Chris Lattner authored Jul 21, 2004
```
        mov %EDI, 12
        add %EDI, %ECX
        mov %ECX, 12
        add %ECX, %EDX
        mov %EDX, 12
        add %EDX, %ESI

instead (really!) generate this:

        add %ECX, 12
        add %EDX, 12
        add %ESI, 12

* Test for whether bits are shifted out during the optzn.

If so, the fold is illegal, though it can be handled explicitly for setne/seteq

This fixes the miscompilation of 254.gap last night, which was a latent bug
exposed by other optimizer improvements.
