The important fix is that the constant interpolation value is stored in the
parameter slot P0, which is encoded as 2.
In addition, drop the SI_INTERP_CONST pseudo instruction, pass the parameter
slot as an operand to V_INTERP_MOV_F32 instead of hardcoding it there, and
add a special operand class for the parameter slots for type checking and
pretty printing.
NOTE: This is a candidate for the Mesa stable branch.

Only implemented for R600 so far. SI is missing implementations of a
few callbacks used by the Indirect Addressing pass and needs code to
handle frame indices.
At the moment R600 only supports array sizes of 16 dwords or less.
Register packing of vector types is currently disabled, which means that a
vec4 is stored in T0_X, T1_X, T2_X, T3_X, rather than T0_XYZW. In order
to correctly pack registers in all cases, we will need to implement an
analysis pass for R600 that determines the correct vector width for each
array.
v2:
- Add support for i8 zext load from stack.
- Coding style fixes
v3:
- Don't reserve registers for indirect addressing when it isn't
being used.
- Fix bug caused by LLVM limiting the number of SubRegIndex
declarations.
v4:
- Fix 64-bit defines

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
