  linux-user: Support stack-grows-up in elfload.c

HPPA is a (the) stack-grows-up target, and supporting that requires
rearranging how we compute addresses while laying out the initial
program stack.  In addition, hppa32 requires 64-byte stack alignment
so parameterize that as well.

  linux-user: Handle TIOCSTART and TIOCSTOP

Some architectures (ppc, alpha, sparc, parisc, sh and xtensa) define the
BSD TIOCSTART and TIOCSTOP ioctls in their kernel headers to provide
compatibility to other operating systems.

Those ioctls are not implemented in Linux, nevertheless, bash will use
this ioctl if it's available on those architectures.

To avoid false warnings, add code to simply ignore those ioctls.

  target-hppa: Add softfloat specializations

Like the original MIPS, HPPA has the MSB of an SNaN set.
However, it has different rules for silencing an SNaN:
(1) msb is cleared and (2) msb-1 must be set if the fraction
is now zero, and (implementation defined) may be set always.
I haven't checked real hardware but chose the set always
alternative because it's easy and within spec.

This is just about the minimum required to enable compilation
without actually executing any instructions.  This contains the
HPPACPU structure and the required callbacks, the gdbstub, the
basic translation loop, and a translate_one function that always
results in an illegal instruction.

  Log Message:
  -----------
  target-hppa: Add nullification framework

The HPPA cpu has a unique form of predicated execution in which
almost any instruction can set the PSW[N] (or "nullify") bit,
which suppresses execution (and even decoding) of the following
instruction.  Execution of a nullified insn clears the PSW[N] bit.

This adds a generic framework for branching over nullified insns,
or for sufficiently simple insns, transforming the writeback of
the result to a conditional move.  In the process, we want to be
able to represent PSW[N] as a TCG condition, which implies management
of the related tcg temps.

  target-hppa: Implement linux-user gateway page

For linux, page 0 is mapped as an execute-only gateway.  A gateway
page is a special bit in the page table that allows a B,GATE insn
within that page to raise processor permissions.  This is how system
calls are implemented for HPPA.

Rather than actually map anything here, or handle permissions at all,
implement the semantics of the actual linux syscall entry points.
