    PR tree-optimization/37021
    * tree-vect-data-refs.c (vect_check_strided_load): Allow
    REALPART/IMAGPART_EXPRs around the supported refs.
    * tree-ssa-structalias.c (find_func_aliases): Assume that
    floating-point values are not used to transfer pointers.

    * gfortran.dg/vect/fast-math-pr37021.f90: New testcase.

relaxes this a tiny bit.
