PR 70687: Use wide_int in combine.c:change_zero_ext

PR 70687 reports a case where combine.c mishandles integer modes
wider than unsigned HOST_WIDE_INT.  I don't have a testcase since
the PR is just pointing out the hole.

Also, I think a ZERO_EXTEND of a vector mode could in principle satisfy
the subreg condition but wouldn't be equivalent to an AND.  E.g.:

      (zero_extend:V4DI (subreg:V4SI (reg:V4DI R) 0))

Simplify cst_and_fits_in_hwi

While looking at the use of cst_and_fits_in_hwi in tree-ssa-loop-ivopts.c,
I had difficulty working out what the function actually tests.  The
final NUNITS check seems redundant, since it asks about the number of
HWIs in the _unextended_ constant.  We've already checked that the
unextended constant has no more than HOST_BITS_PER_WIDE_INT bits, so the
length must be 1.

I think this was my fault, sorry.

Tested on x86_64-linux-gnu and aarch64-linux-gnu.

* tree.c (cst_and_fits_in_hwi): Simplify.

Add a wi::to_wide helper function

As Richard says, we ought to have a convenient way of converting
an INTEGER_CST to a wide_int of a particular precision without
having to extract the sign of the INTEGER_CST's type each time.
This patch adds a wi::to_wide helper for that, alongside the
existing wi::to_offset and wi::to_widest.

Support << and >> for offset_int and widest_int

Following on from the comparison patch, I think it makes sense to
support << and >> for offset_int (int128_t) and widest_int (intNNN_t),
with >> being arithmetic shift.  It doesn't make sense to use
logical right shift on a potentially negative offset_int, since
the precision of 128 bits has no meaning on the target.

Support <, <=, > and >= for offset_int and widest_int

offset_int and widest_int are supposed to be at least one bit wider
than all the values they need to represent, with the extra bits
being signs.  Thus offset_int is effectively int128_t and widest_int
is effectively intNNN_t, for target-dependent NNN.

Because the types are signed, there's not really any need to specify
a sign for operations like comparison.  I think things would be clearer
if we supported <, <=, > and >= for them (but not for wide_int, which
doesn't have a sign).
