tree-optimization/113670 - gather/scatter to/from hard registers

The following makes sure we're not taking the address of hard
registers when vectorizing appearant gathers or scatters to/from
them.

PR tree-optimization/113670
* tree-vect-data-refs.cc (vect_check_gather_scatter):
Make sure we can take the address of the reference base.

* gcc.target/i386/pr113670.c: New testcase.

It's difficult to say when this started because in previous releases another
ICE (PR113622) happens anyway.
