It turned out that I couldn't stop and so fixed a number of other
bugs. All are minor tweaks, well hidden behind the pdt attributes.
Committed as r255311.

PR fortran/82605
* resolve.c (get_pdt_constructor): Initialize 'cons' to NULL.
(resolve_pdt): Correct typo in prior comment. Emit an error if
any parameters are deferred and the object is neither pointer
nor allocatable.
PR fortran/82606
* decl.c (gfc_get_pdt_instance): Continue if the parameter sym
is not present or has no name. Select the parameter by name
of component, rather than component order. Remove all the other
manipulations of 'tail' when building the pdt instance.
(gfc_match_formal_arglist): Emit and error if a star is picked
up in a PDT decl parameter list.
PR fortran/82622
* trans-array.c (set_loop_bounds): If a GFC_SS_COMPONENT has an
info->end, use it rather than falling through to
gcc_unreachable.
(structure_alloc_comps): Check that param->name is non-null
before comparing with the component name.
* trans-decl.c (gfc_get_symbol_decl): Do not use the static
initializer for PDT symbols.
(gfc_init_default_dt): Do nothing for PDT symbols.
* trans-io.c (transfer_array_component): Parameterized array
components use the descriptor ubound since the shape is not
available.
PR fortran/82719
PR fortran/82720
* trans-expr.c (gfc_conv_component_ref): Do not use the charlen
backend_decl of pdt strings. Use the hidden component instead.
* trans-io.c (transfer_expr): Do not do IO on "hidden" string
lengths. Use the hidden string length for pdt string transfers
by adding it to the se structure. When finished nullify the
se string length.
PR fortran/82866
* decl.c (gfc_match_formal_arglist): If a name is not found or
star is found, while reading a type parameter list, emit an
immediate error.
(gfc_match_derived_decl): On reading a PDT parameter list, on
failure to match call gfc_error_recovery.
PR fortran/82978
* decl.c (build_struct): Character kind defaults to 1, so use
kind_expr whatever is the set value.
(gfc_get_pdt_instance): Ditto.
* trans-array.c (structure_alloc_comps): Copy the expression
for the PDT string length before parameter substitution. Use
this expression for evaluation and free it after use.
