Display @entry parameter values even for references.
* ada-valprint.c (ada_val_print_1) <TYPE_CODE_REF>: Try also
coerce_ref_if_computed.

* dwarf2expr.c (dwarf_block_to_dwarf_reg_deref): New function.
(execute_stack_op) <DW_OP_GNU_entry_value>: Add -1 deref_size to the
existing push_dwarf_reg_entry_value call.  Add new detection calling
dwarf_block_to_dwarf_reg_deref.  Update the error message.
(ctx_no_push_dwarf_reg_entry_value): New parameter deref_size.
* dwarf2expr.h
(struct dwarf_expr_context_funcs) <push_dwarf_reg_entry_value>: Add new
parameter deref_size, describe it in the comment.
(ctx_no_push_dwarf_reg_entry_value): Add new parameter deref_size.
(dwarf_block_to_dwarf_reg_deref): New declaration.
* dwarf2loc.c (dwarf_entry_parameter_to_value): Add new parameter
deref_size, describe it in the function comment.  New variables
data_src and size, fetch the alternative block accoring to DEREF_SIZE.
(dwarf_expr_push_dwarf_reg_entry_value): Add new parameter deref_size,
describe it in the function comment.  Fetch the alternative block
accoring to DEREF_SIZE.
(entry_data_value_coerce_ref, entry_data_value_copy_closure)
(entry_data_value_free_closure, entry_data_value_funcs): New.
(value_of_dwarf_reg_entry): New variables checked_type, target_type,
outer_val, target_val, val and addr.  Try to fetch and create also
referenced value content.
(pieced_value_funcs): NULL value for coerce_ref.
(needs_dwarf_reg_entry_value): Add new parameter deref_size.
* f-valprint.c (f_val_print) <TYPE_CODE_REF>: Try also
coerce_ref_if_computed.
* opencl-lang.c (opencl_value_funcs): NULL value for coerce_ref.
* p-valprint.c (pascal_val_print) <TYPE_CODE_REF>: Likewise.
* stack.c (read_frame_arg): Compare also dereferenced values.
* value.c (value_computed_funcs): Make the parameter v const, use
value_lval_const for it.
(value_lval_const, coerce_ref_if_computed): New function.
(coerce_ref): New variable retval.  Call also coerce_ref_if_computed.
* value.h (struct lval_funcs): New field coerce_ref.
(value_computed_funcs): Make the parameter v const.
(value_lval_const, coerce_ref_if_computed): New declarations.

Display @entry parameter values even for references.
* gdb.arch/amd64-entry-value.cc (reference, datap, datap_input): New
functions.
(main): New variables regvar, nodatavarp, stackvar1, stackvar2.  Call
reference and datap_input.
* gdb.arch/amd64-entry-value.exp (reference, breakhere_reference): New
breakpoints.
(continue to breakpoint: entry_reference: reference)
(entry_reference: bt at entry)
