Fixed everywhere for powerpc.  Does hppa still need backports?

We currently use genetic code in hppa_gimplify_va_arg_expr:

static tree
hppa_gimplify_va_arg_expr (tree valist, tree type, gimple_seq *pre_p,
   gimple_seq *post_p)
{
  if (TARGET_64BIT)
{
  /* Args grow upward.  We can use the generic routines.  */
  return std_gimplify_va_arg_expr (valist, type, pre_p, post_p);
}

Log:
rs6000: Small varargs for BE SVR4 (PR61729, PR77850)

The varargs code for SVR4 puts all (integer) arguments in 4-byte slots.
When it then reads an item from there as something not a multiple of 4
bytes, it needs to adjust the address if big endian.  We didn't yet do
that.

This fixes the g++.dg/abi/scoped1.C, gcc.dg/compat/scalar-by-value-4,
and gcc.dg/compat/scalar-return-4 testcases.
