Allow to pass additional options into generator's clang::tooling
In my macOS build, that clang::tooling::runToolOnCodeWithArgs invocation failed
to find headers like cassert and assert.h, which works now with
COMPILER_PLUGINS_TOOLING_ARGS=-isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk -isystem /Users/stephan/Software/llvm/inst/include/c++/v1
added to my autogen.input (I build against my Clang trunk libc++ whose headers
are at /Users/stephan/Software/llvm/inst/include/c++/v1).
