rs6000: insn_cost

This adds an implementation of the insn_cost hook to rs6000.

This implementations is very minimal (so far).  It is mostly based on
how many machine instructions are generated by an RTL insn, and it also
looks at the instruction type.  Floating point insns are costed as if
all machine instructions it generates are floating point; the other
insns are treated as if all but one are integer insns (and one is the
specified type).  Load instructions are treated as costing twice as
much, and load locked and sync insns as three times as much (just like
the original costs), and integer div and mul are handled as well.

Each define_insn (etc.) can set a "cost" attribute to override this
general cost.  With optimization for size, the cost is set equal to the
value of the "length" attribute.

With this, the majority of cost differences between old and new are
where the old was wrong.  Also, benchmarks show a slight win (if
anything).  Some refinements are obviously needed.

Require wi::to_wide for trees

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.

Allow non-wi <op> wi

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

rs6000: Cleanup of various jump patterns

This cleans up formatting of many jump patterns.  Mostly it is writing
output statements as brace blocks, and deleting default arguments.  It
also makes indentation a little bit more consistent, and uses b%T0
(instead of bctr/blr alternatives) in two more places.

* config/rs6000/rs6000.md (conditional branch): Clean up formatting.
Remove empty default arguments.  Use a brace block as output
statement.

rs6000: Update conditional jump patterns, no more (pc) (label_ref)

Currently we have two patterns for every conditional jump: one jumping
if some condition is met, and the other jumping if it is not met.  We
don't need that second form because all our conditions have an opposite
already, and the generic code can deal with that just fine.

This patch deletes that second form.  We generated it directly in one
case; adjusted here.

* config/rs6000/rs6000-string.c (expand_strncmp_align_check): Invert
a conditional jump (and the compare for it) so that pc_rtx is the
