gdb: add type::is_unsigned / type::set_is_unsigned

Browse source 
Add the `is_unsigned` and `set_is_unsigned` methods on `struct type`, in
order to remove the `TYPE_UNSIGNED` macro.  In this patch, the
`TYPE_UNSIGNED` macro is changed to use `type::is_unsigned`, so all the
call sites that are used to set this property on a type are changed to
use the new method.  The next patch will remove the macro completely.

gdb/ChangeLog:

	* gdbtypes.h (struct type) <is_unsigned, set_is_unsigned>: New
	methods.
	(TYPE_UNSIGNED): Use type::is_unsigned.  Change all write call
	sites to use type::set_is_unsigned.
