gallium: PIPE_COMPUTE_CAP_IR_TARGET - allow drivers to specify a processor v2

Browse Source 
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
