Subject: [libcxx] Remove unused macro _LIBCPP_HAS_UNIQUE_TYPEINFO
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9f3561c29232cbd3fa73afdddce7d5c89c41484b;p=platform%2Fupstream%2Fllvm.git

[libcxx] Remove unused macro _LIBCPP_HAS_UNIQUE_TYPEINFO

Summary:
We already have the negation of that as _LIBCPP_HAS_NONUNIQUE_TYPEINFO.
Having both defined is confusing, since only one of them is used.
