Looks like these fix ~90 or so fails with integer enabled..

There are still a pretty big jump in number of fails and crashes
compared to with integer not enabled, but from a quick look I suspect
most of that is unimplemented TGSI opcode's (UIF, AND, etc).. and I
guess a lot of those should be trivial to add.

I'll take a quick stab at adding a few more missing opcodes and see if
we can't cut down the # of fails and crashes..
