Bug 1382525 - Move LLVM_CONFIG out of mozconfig.common. r?chmanchester LLVM_CONFIG, per the contents of toolkit/moz.configure, is tied to --enable-stylo, but it currently is set on all types of builds. It currently happens to work, but it's actually not meant to, and sure enough, the fix for bug 1374727 exacerbates that. So we create a new mozconfig.stylo file that enables stylo and sets LLVM_CONFIG, such that only build types that do enable stylo have LLVM_CONFIG set.
