Wire up the AArch64 EL2 and EL3 address translation operations
(AT S12E1*, AT S12E0*, AT S1E2*, AT S1E3*), and correct some
errors in the ats_write64() function in previously unused code
that would have done the wrong kind of lookup for accesses from
EL3 when SCR.NS==0.

The op is sometimes named trunc_shr_i32 and sometimes trunc_shr_i64_i32,
and the name in the README doesn't match the name offered to the
frontends.
Always use the long name to make it clear it is a size changing op.

This patchset improves the optimizer in 3 different ways:
- by optimizing temp tracking using a bit array
- by allowing constants to have copy
- by differentiating 32 - 64 bits conversions from moves in the
frontend by using specific instructions
The latter change introduces 2 new mandatory
Implement real ext_i32_i64 and extu_i32_i64 ops. They ensure that a
32-bit value is always converted to a 64-bit value and not propagated
through the register allocator or the optimizer.

Now that we have real size changing ops, we don't need to mark high
bits of the destination as garbage. The goal of the optimizer is to
predict the value of the temps (and not of the registers) and do
simplifications when possible. The problem there is therefore not the
fact that those bits are
Now that copies and constants are tracked separately, we can allow
constant to have copies, deferring the choice to use a register or a
constant to the register allocation pass. This prevent this kind of
regular constant reloading:

+OUT: [size=298]

For EL2 stage 1 translations, there is no TTBR1. We were already

This patch series wires up some of the EL2 and EL3 address
translation operations which we were missing:
* the AArch64 EL2 and EL3 AT ops
* the AArch32 ATS12NSO ops
* the AArch32 ATS1H ops
Most of these are still not accessible or not very interesting
because we don't have any CPUs which set

Apply the correct conditions in the ats_access() function for
the ATS12NSO* address translation operations:
* succeed at EL2 or EL3
* normal UNDEF trap from NS EL1
* trap to EL3 from S EL1 (only possible if EL3 is AArch64)
