Recommit of r361790 that was temporarily reverted in r361793 due to bot breakage. Summary: The following changes were required to fix these tests: 1) Change LLVM_ENABLE_PLUGINS to an option and move it to llvm/CMakeLists.txt with an appropriate default -- which matches the original default behavior. 2) Move the plugins directory from clang/test/Analysis clang/lib/Analysis. It's not enough to add an exclude to the lit.local.cfg file because add_lit_testsuites recurses the tree and automatically adds the appropriate `check-` targets, which don't make sense for the plugins because they aren't tests and don't have `RUN` statements. Here's a list of the `clang-check-anlysis*` targets with this change: ``` $ ninja -t targets all| sed -n "s/.*\/\(check[^:]*\):.*/\1/p" | sort -u | grep clang-analysis check-clang-analysis check-clang-analysis-checkers check-clang-analysis-copypaste check-clang-analysis-diagnostics check-clang-analysis-engine check-clang-analysis-exploration_order check-clang-analysis-html_diagnostics check-clang-analysis-html_diagnostics-relevant_lines check-clang-analysis-inlining check-clang-analysis-objc check-clang-analysis-unified-sources check-clang-analysis-z3 ``` 3) Simplify the logic and only include the subdirectories under clang/lib/Analysis/plugins if LLVM_ENABLE_PLUGINS is set.
