add signed_bool_precision attribute for GIMPLE FE use
This adds __attribute__((signed_bool_precision(precision))) to be able
to construct nonstandard boolean types which for the included testcase
is needed to simulate Ada and LTO interaction (Ada uses a 8 bit
precision boolean_type_node). This will also be useful for vector
unit testcases where we need to produce vector types with
non-standard precision signed boolean type components.
