tree-optimization/115597 - allow CSE of two-operator VEC_PERM nodes
The following makes sure to always CSE when there's SLP_TREE_SCALAR_STMTS
as otherwise a chain of two-operator node operations can result in
exponential behavior of the CSE process as likely seen when building
510.parest on aarch64.

* tree-vect-slp.cc (vect_cse_slp_nodes): Allow to CSE
VEC_PERM nodes.
