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
