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

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,

In form_gva and cpu_get_tb_cpu_state, we must truncate when PSW_W == 0.
