This patchset adds emulation support and tests for setb instruction.
Test cases are written to test different CR fields with different
bits set in each field.

v1->v2:
  - Extract all the bits of the CR field (bfa) and check if the
    LT, GT bits of that CR field (bfa) are set.
  - Place 'setb' emulation code after 'mfcr' instruction emulation.
  - Add 'cpu_feature' in the selftests patch to restrict them to ISA v3.0
