The conversions to/from i64 can be eliminated entirely,
folding computation into adjacent operations.

Rename the existing insert tlb helpers to emphasize that they
are for pa1.1 cpus. Implement a combined i/d tlb for pa2.0.
Still missing is the new 'P' tlb bit.

Allow both user-only and system mode to run pa2.0 cpus.
Avoid creating a separate qemu-system-hppa64 binary;
force the qemu-hppa binary to use TARGET_ABI32.

There is no support for hppa64 in gdb. Any attempt to provide the
data for the larger hppa64 registers results in an error from gdb.
Mask CR_SAR writes to the width of the register: 5 or 6 bits.

Hoist the resolution of d up one level above do_unit_cond.
All computations are logical, and are simplified by using a mask of the
correct width, after which the result may be compared with zero.

The sar shift amount register is limited to 5 bits when running
a 32-bit CPU. Strip off the remaining bits.
The interesting part is, that this register allows to detect at runtime
if a physical CPU is capable to execute PA2.0 (64-bit) instructions.

We need to make sure the link is masked properly along the
use_nullify_skip path. The other three settings of a link
register already use this.

This will be how we ensure that the IAOQ is always
valid per PSW.W, therefore all stores to these two
variables must be done with this function.
Use third argument -1 if the destination is always dynamic,
and fourth argument NULL if the destination is always static.

In form_gva and cpu_get_tb_cpu_state, we must truncate when PSW_W == 0.
In space_select, the bits that choose the space depend on PSW_W.
