Combine disabled this optimization in r10-254-gddbb5da5199fb42 but it makes
sense to do this on the gimple level and then let expand decide which way is
better. So this adds the transformation on the gimple level (late like was
done for the multiply case).

From: Andrew Pinski
The pattern here was not catching all comparisons and the multiply
was not commutative when it should have been. This patches fixes
that by using tcc_comparison and adding :c to the multiply.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

This second patch completes the work of the first 'array-copy' patch to
provide first-cut implementations of all P1997 features. It adds:
* Assignments to arrays from array values,a = b;
* Placeholder auto in array declarations, auto cp[] = a;
* Array as a return type from functions WIP
This patch implements initializations of arrays from array values.
The first of two 'array-copy' patches, it adds the option -farray-copy
(flag_array_copy) to enable all features of P1997 (copy related or not),
documented as experimental extensions.
It deals with initialization of array variables
Also address "FIXME: this code is duplicated from reshape_init" in
cp_complete_array_type by always calling reshape_init on init-list.

* array-array assignments
* array return-by-value from functions

A recent thread on this mailing list made me remember that this proposal
is still open.
I've updated it just to add a missing std qualification.

Let's have a look at the tree-dump of the existing testcase:
integer(kind=4) runtime_poppar (integer(kind=16) & restrict i)
{
integer(kind=4) res;
{
uint128_t D.4221;
D.4221 = (uint128_t) *i;
res = __builtin_parityll ((unsigned long) D.4221 ^ (unsigned long)
(D.4221 >> 64));
