This is the pa2.0 cpu that should populate Helge's C3700 workstation.

I have adjusted both user and system binaries to always support the
64-bit cpu but default to the 32-bit cpu.

I have not yet copied the linux kernel sigframe hackery to save
the upper halves of the registers across signals.  I couldn't get
hppa-linux-gcc to produce 64-bit code with -march=2.0.  I did some
some manual testing with hppa64-linux-gnu, but that expects lp64
and a full 64-bit system library, so the tests has to be small
and self-contained and also required some manual adjustment for
the .got pointer references.

Changes for v2:
  * Rebased, fixing conflicts with the now merged C3700.
  * hppa_is_pa20 uses classes, like riscv_cpu_is_dynamic.
