functions.
(dwarf2_locexpr_funcs): Install locexpr_read_variable_at_entry.
(loclist_read_variable_at_entry): New function.
(dwarf2_loclist_funcs): Install loclist_read_variable_at_entry.
* dwarf2read.c (read_call_site_scope): Support also DW_OP_fbreg in
DW_AT_location, call dwarf_block_to_sp_offset for it.

* mi/mi-cmd-stack.c (list_arg_or_local): New gdb_assert for
arg->entry_kind. Optionally print the `@entry' suffix.
(list_args_or_locals): New variable entryarg, initialize it.
Initialize also entry_kind of arg and entryarg. Conditionalize
list_arg_or_local for arg, add list_arg_or_local for entryarg. Call
xfree for entryarg.error.

print the `@entry' suffix, possibly in combination for
print_entry_values_compact.
(read_frame_arg): New parameter entryargp, new variables entryval,
entryval_error and val_equal. Read in also entryargp, respect
print_entry_values, compare the values using val_equal, fill in also
argp->entry_kind (together with entryargp->entry_kind).
(print_frame_args): New variable entryarg, initialize it.
Conditionalize print_frame_arg for arg, add print_frame_arg for
entryarg. Call xfree for entryarg.error.
(_initialize_stack): Call add_setshow_enum_cmd for `entry-values'.
