    vect: Fix ncopies calculation for emulated gather/scatter [PR103494]

    I was too eager about removing ncopies calculations in g:10833849b55.
    When emulating gather/scatter, the offset ncopies can be different from
    the data ncopies.  This patch restores the original calculation.

    gcc/
            PR tree-optimization/103494
            * tree-vect-stmts.c (vect_get_gather_scatter_ops): Remove ncopies
            argument and calculate ncopies from gs_info->offset_vectype
            where necessary.
            (vectorizable_store, vectorizable_load): Update accordingly.

    gcc/testsuite/
            PR tree-optimization/103494
            * gcc.dg/vect/pr103494.c: New test.
            * g++.dg/vect/pr103494.cc: Likewise.
