It turns out that setting the clang module cache after LLDB has a Target can be too late. In particular, the Swift language plugin needs to know the setting without having access to a Target. This patch moves the setting into the *LLDB* module cache, where it is a global setting that is available before any Target is created and more importantly, is shared between all Targets. rdar://problem/37944432 Differential Revision: https://reviews.llvm.org/D43984 llvm-svn: 326628
