ilo: add a toy shader compiler
This is a simple shader compiler that performs almost zero optimizations. The
generated code is usually much larger comparing to that generated by i965.
The generated code also requires many more registers.
Function-wise, it lacks register spilling and does not support most TGSI
indirections. Other than those, it works alright.
