    Fortran: fix passing of component ref to assumed-rank dummy [PR118683]
    
    While the fix for pr117774 addressed the passing of an inquiry reference
    to an assumed-rank dummy, it missed the similar case of passing a component
    reference.  The newer testcase gfortran.dg/pr81978.f90 uncovered this
    latent issue with a UBSAN instrumented compiler.

    gcc/fortran/ChangeLog:
    
            * trans-expr.cc (gfc_conv_procedure_call): The bounds update for
            passing to assumed-rank dummies shall also handle component
            references besides inquiry references.
