    Fortran: Fixes and additional tests for shape/ubound/size [PR94070]

    This patch reimplements the SHAPE intrinsic to be inlined similarly to
    LBOUND and UBOUND, instead of as a library call, to avoid an
    unnecessary array copy.  Various bugs are also fixed.

            PR fortran/94070

            * expr.c (gfc_simplify_expr): Handle GFC_ISYM_SHAPE along with
            GFC_ISYM_LBOUND and GFC_ISYM_UBOUND.
            * trans-array.c (gfc_conv_ss_startstride): Likewise.
            (set_loop_bounds): Likewise.
            * trans-intrinsic.c (gfc_trans_intrinsic_bound): Extend to
            handle SHAPE.  Correct logic for zero-size special cases and
            detecting assumed-rank arrays associated with an assumed-size
            argument.
            (gfc_conv_intrinsic_shape): Deleted.
            (gfc_conv_intrinsic_function): Handle GFC_ISYM_SHAPE like
            GFC_ISYM_LBOUND and GFC_ISYM_UBOUND.
            (gfc_add_intrinsic_ss_code): Likewise.
