R600/SI: Prefer SALU instructions for bit shift operations

All shift operations will be selected as SALU instructions and then
if necessary lowered to VALU instructions in the SIFixSGPRCopies pass.

This allows us to do more operations on the SALU which will improve
performance and is also required for implementing private memory
using indirect addressing, since the private memory pointers must stay
in the scalar registers.

This patch includes some fixes from Matt Arsenault.

R600/SI: Add support for private address space load/store

Private address space is emulated using the register file with
MOVRELS and MOVRELD instructions.
