r266734 has introduced a new instance of jump threading pass in order to
take advantage of opportunities that combine opens up.  It was perceived
back then that it was beneficial to delay it after reload, since that
might produce even more such opportunities.

Unfortunately jump threading interferes with hot/cold partitioning.  In
the code from PR92007, it converts the following

  +-------------------------- 2/HOT ------------------------+
  |                                                         |
  v                                                         v
3/HOT --> 5/HOT --> 8/HOT --> 11/COLD --> 6/HOT --EH--> 16/HOT
            |                               ^
            |                               |
            +-------------------------------+

into the following:

  +---------------------- 2/HOT ------------------+
  |                                               |
  v                                               v
3/HOT --> 8/HOT --> 11/COLD --> 6/COLD --EH--> 16/HOT

This makes hot bb 6 dominated by cold bb 11, and because of this
fixup_partitions makes bb 6 cold as well, which in turn makes EH edge
6->16 a crossing one.  Not only can't we have crossing EH edges, we are
also not allowed to introduce new crossing edges after reload in
general, since it might require extra registers on some targets.

Therefore, move the jump threading pass between combine and hot/cold
partitioning.  Building SPEC 2006 and SPEC 2017 with the old and the new
code indicates that:

* When doing jump threading right after reload, 3889 edges are threaded.
* When doing jump threading right after combine, 3918 edges are
  threaded.

This means this change will not introduce performance regressions.

In PR88760, there are a few disscussion about improve or tune unroller for
targets. And we would agree to enable unroller for small loops at O2 first.
And we could see performance improvement(~10%) for below code:
```
  subroutine foo (i, i1, block)
    integer :: i, i1
    integer :: block(9, 9, 9)
    block(i:9,1,i1) = block(i:9,1,i1) - 10
  end subroutine foo

```
This kind of code occurs a few times in exchange2 benchmark.

Similar C code:
```
  for (i = 0; i < n; i++)
    arr[i] = arr[i] - 10;
```

On powerpcle, for O2 , enable -funroll-loops and limit
PARAM_MAX_UNROLL_TIMES=2 and PARAM_MAX_UNROLLED_INSNS=20, we can see >2%
overall improvement for SPEC2017.

This patch is only for rs6000 in which we see visible performance improvement.

When we have -fstack-limit-symbol with sysv we can end up with a non-
existing instruction (you cannot add an immediate to register 0).  Fix
this by using register 11 instead.  It might be used for something else
already though, so save and restore its value around this.  In
optimizing compiles these extra moves are usually removed again: the
restore by cprop_hardreg, and then the save by rtl_dce.

Unwanted unrolling meant that we had more single-precision FADDAs

Recent target-independent patches mean that several SVE tests
now produce the code that we'd originally wanted them to produce.
Really nice to see :-)

This patch therefore updates the expected baseline, so that hopefully
we don't regress from this point in future.

Now that vectorizable_operation vectorises most loop stmts involved
in a reduction, it needs to be aware of reductions in fully-masked loops.
The LOOP_VINFO_CAN_FULLY_MASK_P parts of vectorizable_reduction now only
apply to cases that use vect_transform_reduction.

This new way of doing things is definitely an improvement for SVE though,
since it means we can lift the old restriction of not using fully-masked
loops for reduction chains.
