LTO code may end up mixing bitcode files from various sources varying in their use of opaque pointer types. The current strategy to decide between opaque / typed pointers upon the first bitcode file loaded does not work here, since we could be loading a non-opaque bitcode file first and would then be unable to load any files with opaque pointer types later. So for LTO this: - Adds an `lto::Config::OpaquePointer` option and enforces an upfront decision between the two modes. - Adds `-opaque-pointers`/`-no-opaque-pointers` options to the gold plugin; disabled by default. - `--opaque-pointers`/`--no-opaque-pointers` options with `-plugin-opt=-opaque-pointers`/`-plugin-opt=-no-opaque-pointers` aliases to lld; disabled by default. - Adds an `-lto-opaque-pointers` option to the `llvm-lto2` tool. - Changes the clang driver to pass `-plugin-opt=-opaque-pointers` to the linker in LTO modes when clang was configured with opaque pointers enabled by default.
