3dbb504081 Fix cases where we generated horrible code like this:
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

7d02766247 Include <iostream> here, because most people using DEBUG() want to use std::cerr too.
This means that users of this file do not also need to include <iostream>.

a31f1f7cb2 * Add the lost fix to define the second reg of a 2-reg representation of longs

f0cacc0ae7 * Further cleanup.
* 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.
