Fill in the insn_start value during form_gva, and copy
it out to the env field in hppa_restore_state_to_opc.
The value is not yet consumed.

The previous decoding misnamed the bit it called "local".
Other than the name, the implementation was correct for pa1.x.
Rename this field to "tlbe".

PA2.0 adds (a real) local bit to PxTLB, and also adds a range
of pages to flush in GR[b].

These are aliased onto the normal integer loads to %g0.
Since we don't emulate caches, prefetch is a nop.

The default PSW is set by the operating system with the PDC_PSW
firmware call.  Use that setting to decide if wide mode is to be
enabled for interruptions and EIRR usage.

Split out the tlb to a subsection so that it can be separately
versioned -- the format is only partially following the architecture
and is partially guided by the qemu implementation.

The conversions to/from i64 can be eliminated entirely,

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.
