    rs6000: Fix restored rs6000_long_double_type_size

    As mentioned in the "Fallout: save/restore target options in
handle_optimize_attribute"
    thread, we need to support target option restore
    of rs6000_long_double_type_size == FLOAT_PRECISION_TFmode.

    gcc/ChangeLog:

            * config/rs6000/rs6000.c (rs6000_option_override_internal): When
            a target option is restored, it can have
            rs6000_long_double_type_size set to FLOAT_PRECISION_TFmode
            and error should not be emitted.

    gcc/testsuite/ChangeLog:

            * gcc.target/powerpc/pragma-optimize.c: New test.
