This patch replaces the REDUC_*_EXPR tree codes with internal functions.
This is needed so that the upcoming in-order reductions can also use
internal functions without too much complication.

The wide_int routines allow things like:
wi::add (t, 1)
to add 1 to an INTEGER_CST T in its native precision. But we also have:
wi::to_offset (t) // Treat T as an offset_int
wi::to_widest (t) // Treat T as a widest_int
Recently we also gained:
wi::to_wide (t, prec) // Treat T as a wide_int in preccision PREC
This patch therefore requires:
wi::to_wide (t)
when operating on INTEGER_CSTs in their native precision. This is
just as efficient, and makes it clearer that a deliberate choice is
being made to treat the tree as a wide_int in its native precision.
This also removes the inconsistency that
a) INTEGER_CSTs in their native precision can be used without an accessor
but must use wi:: functions instead of C++ operators
b) the other forms need an explicit accessor but the result can be used
with C++ operators.
It also helps with SVE, where there's the additional possibility
that the tree could be a runtime value.

This patch uses global rather than member operators for wide-int.h,
so that the first operand can be a non-wide-int type.
The patch also removes the and_not and or_not member functions.
It was already inconsistent to have member functions for these
two operations (one of which was never used) and not other wi::
ones like udiv. After the operator change, we'd have the additional
inconsistency that "non-wi & wi" would work but "non-wi.and_not (wi)"
wouldn't.

This patch makes can_vec_perm_p & co. take a vec<>, wrapped in new
typedefs vec_perm_indices and auto_vec_perm_indices. There are two
reasons for doing this for SVE:
(1) it means that the number of elements is bundled with the elements
themselves, and is obviously constant.
(2) it makes it easier to change the "unsigned char" element type to
something wider.
Changing the target hook is left as follow-on work.

This patch makes build_vector take the elements as a vec<> rather
than a tree *. This is useful for SVE because it bundles the number
of elements with the elements themselves, and enforces the fact that
the number is constant. Also, I think things like the folds can be used
with any generic GNU vector, not just those that match machine vectors,
so the arguments to XALLOCAVEC had no clear limit.

Previously VECTOR_CST_NELTS (t) read the number of elements from
TYPE_VECTOR_SUBPARTS (TREE_TYPE (t)). There were two ways of handling
this with variable TYPE_VECTOR_SUBPARTS: either forcibly convert the
number to a constant (which is doable) or store the number directly
in the VECTOR_CST. The latter seemed better, since it involves less
pointer chasing and since the tree_node u field is otherwise unused
for VECTOR_CST. It would still be easy to switch to the former in
future if we need to free up the field for someting else.
The patch also changes various bits of VECTOR_CST code to use
VECTOR_CST_NELTS instead of TYPE_VECTOR_SUBPARTS when iterating
over VECTOR_CST_ELTs. Also, when the two are checked for equality,
the patch prefers to read VECTOR_CST_NELTS (which must be constant)
and check against TYPE_VECTOR_SUBPARTS, instead of the other way
around.

get_best_mode always returns a scalar_int_mode on success,
so this patch makes that explicit in the type system. Also,
the "largest_mode" argument is used simply to provide a maximum
size, and in practice that size is always a compile-time constant,
even when the concept of variable-sized modes is added later.
The patch therefore passes the size directly.

This patch adds a macro that extracts the TYPE_MODE and forcibly
converts it to a scalar_float_mode. The forcible conversion
includes a gcc_checking_assert that the mode is a SCALAR_FLOAT_MODE_P.
This becomes important as more static type checking is added by
later patches. It has the additional benefit of bypassing the
VECTOR_TYPE_P (...) ? vector_type_mode (...) : ... condition
in TYPE_MODE; in release builds the new macro is a simple
field access.
