fc0d441e14 Fix CR ops with complement, thanks to Julian Seward for testing 
and reporting the bug :
* remove bugged CR ops specific micro-ops
* use standard and / or / shift operations instead
* comment not-used-anymore op_store_T1_crf_crf micro-op template.

6ebbf39000 Replace is_user variable with mmu_idx in softmmu core, 
allowing support of more than 2 mmu access modes.
Add backward compatibility is_user variable in targets code when needed.
Implement per target cpu_mmu_index function, avoiding duplicated code
  and #ifdef TARGET_xxx in softmmu core functions.
Implement per target mmu modes definitions. As an example, add PowerPC
  hypervisor mode definition and Alpha executive and kernel modes definitions.
Optimize PowerPC case, precomputing mmu_idx when MSR register changes
  and using the same definition in code translation code.
