Add opt-viewer testing Detects whether we have the Python modules (pygments, yaml) required by opt-viewer and hooks this up to REQUIRES. This fixes https://bugs.llvm.org/show_bug.cgi?id=34129 (the lack of opt-viewer testing). It's also related to https://github.com/apple/swift/pull/12938 and the idea is to expose LLVM_HAVE_OPT_VIEWER_MODULES to the Swift cmake. Differential Revision: https://reviews.llvm.org/D40202 Fixes since the first commit: 1. Disable syntax highlighting as different versions of pygments generate different HTML 2. Use llvm-cxxfilt from the build llvm-svn: 319324 2017-11-30 01:07:41 +08:00			`if 'have_opt_viewer_modules' not in config.available_features:`
