db9fbb2b79 AMDGPU: Switch barrier intrinsics to using convergent 
noduplicate prevents unrolling of small loops that happen to have
barriers in them. If a loop has a barrier in it, it is OK to duplicate
it for the unroll.

1adcdc6e96 AMDGPU: Add sdst operand to VOP2b instructions 
The VOP3 encoding of these allows any SGPR pair for the i1
output, but this was forced before to always use vcc.
This doesn't yet try to use this, but does add the operand
to the definitions so the main change is adding vcc to the
output of the VOP2 encoding.
