9f7818d9bd R600: rework handling of the constants 
Remove Cxxx registers, add new special register - "ALU_CONST" and new
operand for each alu src - "sel". ALU_CONST is used to designate that the
new operand contains the value to override src.sel, src.kc_bank, src.chan
for constants in the driver.

Patch by: Vadim Girlin

Vincent Lejeune:
  - Use pointers for constants
  - Fold CONST_ADDRESS when possible

Tom Stellard:
  - Give CONSTANT_BUFFER_0 its own address space
  - Use integer types for constant loads
