Log message:
	* builtins.def (BUILT_IN_STACK_ALLOC): Remove.
	* builtins.c (expand_builtin) <BUILT_IN_STACK_ALLOC>: Remove.
	* dwarf2out.c (loc_descriptor): Handle PARALLEL here ...
	(add_location_or_const_value_attribute): ... not here.  Use
	loc_descriptor_from_tree if possible.
	(loc_descriptor_from_tree_1): Rename from loc_descriptor_from_tree.
	Simplify address handling.  Handle DECL_VALUE_EXPR.  Handle register
	values specially.
	(loc_descriptor_from_tree): New.  Update callers.
	* expr.c (expand_var): Ignore DECL_VALUE_EXPR variables.
	* gimplify.c (gimplify_decl_expr): Lower variable sized types to
	pointer plus dereference.  Set DECL_VALUE_EXPR.  Set save_stack.
	(gimplify_call_expr): Do not recognize BUILT_IN_STACK_ALLOC
	and BUILT_IN_STACK_RESTORE.
	(gimplify_expr): Lower DECL_VALUE_EXPR decls.
	* stmt.c (expand_stack_alloc): Remove.
	* tree-mudflap.c (mx_register_decls): Don't look for
	BUILT_IN_STACK_ALLOC.
	* tree-nested.c (convert_local_reference): Likewise.
	* tree.h (DECL_VALUE_EXPR): New.
	ada/
	* utils.c (gnat_install_builtins): Remove __builtin_stack_alloc,
	add __builtin_alloca.
	fortran/
	* f95-lang.c (gfc_init_builtin_functions): Remove
	__builtin_stack_alloc, add __builtin_alloca.
	* trans-array.c (gfc_trans_auto_array_allocation): Use DECL_EXPR.
	* trans-decl.c (gfc_trans_auto_character_variable): Likewise.
