[PATCH] TS_OPTIMIZATION/TS_TARGET_OPTION need no chain/type

[Richard Biener]

LTO bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

(most "gross" are still TS_LIST having a type and TS_VEC having type
and chain, but that's been hard to fix with the C++ FE in place)

Richard.

        * tree.c (initialize_tree_contains_struct): Make TS_OPTIMIZATION
        and TS_TARGET_OPTION directly derive from TS_BASE.
