Remove support for assigning to `this'.
* NEWS: Note that fact.
* class.c (build_vbase_path): Don't check flag_this_is_variable.
* cp-tree.h (EXPR_STMT_ASSIGNS_THIS): Remove.
(language_function): Remove assigns_this, just_assigned_this, and
x_base_init_expr. Add x_vcalls_possible_p. Add vtbls_set_up_p.
(base_init_expr): Remove.
(current_vcalls_possible_p): New macro.
(vtbls_set_up_p): Likewise.
(emit_base_init): Change prototype.
* decl.c (finish_destructor_body): New function, split out from
finish_function.
(current_function_assigns_this): Remove.
(current_function_just_assigned_this): Likewise.
(start_function): Don't set them.
(finish_function): Don't check them. Don't emit
base-initialization code here. Generate code for destructors when
doing semantic analysis.
(finish_stmt): Don't check current_function_just_assigned_this.
* decl2.c (lang_f_options): Remove this-is-variable.
(lang_decode_option): Likewise.
(grokclassfn): Don't check flag_this_is_variable.
* init.c (emit_base_init): Return the expression generated.
(construct_virtual_bases): Don't push/pop obstacks. Fix
typo.
(build_new_1): Don't check flag_this_is_variable.
(get_temp_regvar): Don't set DECL_REGISTER.
(build_vec_init): Don't call use_variable.
* lang-options.h: Remove "-fthis-is-variable" and
"-fno-this-is-variable".
* pt.c (tsubst_expr): Don't check EXPR_STMT_ASSIGNS_THIS.
* search.c (expand_upcast_fixups): Use finish_expr_stmt, not
expand_expr_stmt.
* semantics.c (finish_expr_stmt_real): Rename to ...
(finish_expr_stmt): This. Remove assigned_this parameter.
(begin_if_stmt): Call do_pushlevel before starting the statement.
(begin_compound_stmt): Don't declare __FUNCTION__ in scope-less
blocks.
(setup_vtbl_ptr): Emit initialization code for bases and members
at semantic-analysis time. Emit code to initialize vtables in
destructors here.
(expand_stmt): Use finish_expr_stmt, not finish_expr_stmt_real.
Don't handle CTOR_INITIALIZER any more.
* typeck.c (build_modify_expr): Don't check for assignments to
this.
(c_expand_return): Don't suggest assigning to `this'.
* Makefile.in (decl.o): Depend on RTL_H.
(decl2.o): Likewise.
(class.o): Likewise.
(call.o): Likewise.
(method.o): Likewise.
(search.o): Likewise.
(tree.o): Likewise.
(pt.o): Likewise.
* decl.c (duplicate_decls): When a builtin function is redeclared
as static, make sure it is mangled correctly.
* ir.texi (CTOR_INITIALIZER): Remove mention. Fix typo. Add
detail about the statement-tree.
