[Mesa-dev] R600: Expand integer operations for SI and consolidate code with EG

[Aaron Watry]

This series is intended to bring SI closer to evergreen when it comes to
support for v2i32/v4i32 integer operations.

It adds support for expanding the following v2i32/v4i32 operations on SI:
AND, MUL, OR, SHL, SRL, ASHR, UDIV, UREM, XOR

Once that's done, the setOperationAction(op,type,Expand) calls that appear in
both R600ISelLowering.cpp and SIISelLowering.cpp are all moved to
AMDGPUISelLowering.cpp.  If we decide to implement these ops through native
instructions for either target in the future, we can override that in the
individual targets.
