Fix reading of cpu_lock in gen_qemu_stql_c, original patch from Laurent
Desnogues.
A new flag was added to gen_store_mem to allocate local temps instead
of temps; this flag should be set when the tcg_gen_qemu_store callback
uses brcond before using the temps or else liveness analysis will get
rid of the temps.
This also adds lock printing in cpu_dump_state which can help
debug.

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.
