gallium: PIPE_COMPUTE_CAP_IR_TARGET - allow drivers to specify a processor v2
This target string now contains four values instead of three. The old
processor field (which was really being interpreted as arch) has been split
into two fields: processor and arch. This allows drivers to pass a
more a more detailed description of the hardware to compiler frontends.
v2:
- Adapt to libclc changes
