Recognize popcount also when a double width operation is needed.

* match.pd <popcount & / + pattern matching>:
When generating popcount directly fails, try doing it in two halves.
gcc/testsuite/
* gcc.dg/tree-ssa/popcount4ll.c: Remove lp64 condition.
Adjust scanning pattern for !lp64.
* gcc.dg/tree-ssa/popcount5ll.c: Likewise.
* gcc.dg/tree-ssa/popcount4l.c: Adjust scanning pattern
for ! int32plus.
