PS1 = Copy tools/clang/plugin to tools/clang/raw_ptr_plugin
and rename FindBadConstructs* into RawPtrPlugin*.
Since it is not possible for clang plugins to depend //base, plugins
cannot depend on scoped_refptr. Instead, they use banned
std::shared_ptr. Since //tools/clang/plugins uses std::shared_ptr,
raw_ptr_plugin also uses it. To avoid chromium_presubmit, we need
to use No-Presubmit: true for this CL.
Change-Id: I19cb30740fabb006d991889e64a0abd9742b9b5f
No-Presubmit: true
