(smallest_mode_for_size): New function.
(variable_size): Allow variable sizes if global_bindings_p returns a negative
value.
(mode_for_size): Fix incorrect comment.
(layout_decl): If DECL has a size already, don't copy from type.
(layout_type, case INTEGER_TYPE, ENUMERAL_TYPE): Use smallest integer mode
that fits, whether or not it fits exactly.

object whose address is being taken is safe from X.
(expand_expr): Fix misplaced comment from last change.
(expand_expr, case *_DECL): If not already used, assemble external.
(expand_expr, case EXIT_EXPR): Simplify.
(expand_expr, TRUTH_{AND,OR}IF_EXPR): Properly handle IGNORE case.

(init_decl_processing): When making SIZETYPE, start with name in
SIZE_TYPE.  If -traditional, use a signed version of that type, if it
is unsigned.

({l,r}{shift,rotate}_double): COUNT arg is HOST_WIDE_INT, PREC is int.

(subst, case IF_THEN_ELSE): Make a shift when appropriate.
(simplify_shift_const): If we have an outer operation and made a shift, see if
it can be simplified.

From-SVN: r4748

(do_store_flag): When computing via a shift, allow for an inner RSHIFT_EXPR
in BITNUM.
Sometimes do the operations as signed.

(fold_truthop): Treat a BIT_AND_EXPR with a constant of one as if it were
surrounded with an NE_EXPR.
(fold): Don't move operation into conditional if it is BIT_{AND,OR}_EXPR with
the constant 1; change it to TRUTH_*_EXPR instead.
When moving things inside conditions, move comparisons as well as binary
operations.
Don't make a SAVE_EXPR when moving things inside conditionals unless the value
would really have been used twice.
