Bug: http://b/187231324 This script parses soong/cc/config/global.go to return clang prebuilts version. (It may get the version from a json config file in the future.) Currently it's used in development/scripts/symbol.py and is the recommended way to get clang prebuilts version number in the future. Test: get_clang_version_test.py Change-Id: Id92a74fd523a5270999bb4d6454525bf2f2f0c04
