improve compatibility of concatenation (bug #33966) * op-cell.cc (oct_catop_cell_matrix, oct_catop_matrix_cell): Delete concatenation functions. (install_cell_ops): Don't install them. * ov-bool.h (octave_bool::int8_scalar_value, octave_bool::int16_scalar_value, octave_bool::int32_scalar_value, octave_bool::int64_scalar_value, octave_bool::uint8_scalar_value, octave_bool::uint16_scalar_value, octave_bool::uint32_scalar_value, octave_bool::uint64_scalar_value): New functions. * pt-mat.cc: New tests for concatentation. (tree_matrix::rvalue1): Special case cell concatentation. (eval_error): Don't print line and column info. Change all callers. (tm_row_const::tm_row_const_rep::do_init_element) (tm_row_const::tm_row_const_rep::any_cell, tm_row_const::tm_row_const_rep::first_elem_is_struct): New data members. Adjust constructor initialization lists. (tm_row_const::any_cell_p): New function. (get_concat_class): Give structs and cells proper precedence. Handle "class". (tm_row_const::tm_row_const_rep::do_init_element): Check for cells and whether the first element is a struct. Don't check dimensions here. (tm_row_const::tm_row_const_rep::init): Convert expressions to values here. Maybe convert list elements to cells. Check dimensions.
