970d622e8a target-alpha: fix cmpbge instruction
The cmpbge instruction should compare all 8 bytes of one 64-bit value with
another.  However, we were looping with a < 7 condition which was skipping
the top byte.  So if we were doing a compare where the top byte was
important, we could get the wrong result (this notably breaks the strlen()
function with certain sized strings).

57a92c8e36 target-alpha: fix locked loads/stores
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.

1304ca878a target-alpha: Fix ret instruction
Hopefully pine doesn't corrupt this patch, I've had problems recently.

For an alpha "ret" instruction, of the type
     ret $26

The return was being ignored.  This is because in translate.c
register $26 (the return address) was being over-written with the current
PC before it could be jumped to.  Thus the ret was ignored.

This patch just re-orders things so the return address is processed before
it is over-written with the current PC.

9e85e9bdcf alpha: fix lit sign
according to the alpha arch reference, the literal field of an operate
instruction is unsigned:

If bit <12> of the instruction is 1, an 8-bit zero-extended literal
constant is formed by bits
<20:13> of the instruction. The l teral is interpreted as a positive
integer bet ween 0 and 255
and is zero-extended to 64 bits.

This patch fixes the mis-interpretation of the literal field.

Operation:

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.
