Reland 4: [analyzer] NFC: Update test infrastructure to support multiple constraint managers Summary: Replace calls to %clang/%clang_cc1 with %clang_analyze_cc1 when invoking static analyzer, and perform runtime substitution to select the appropriate constraint manager, per D28952.

Add an option to silence all analyzer warnings. People have been incorrectly using "-analyzer-disable-checker" to silence analyzer warnings on a file, when analyzing a project. Add the "-analyzer-disable-all-checks" option, which would allow the suppression and suggest it as part of the error message for "-analyzer-disable-checker". The idea here is to compose this with "--analyze" so that users can selectively opt out specific files from static analysis. llvm-svn: 216763
