[frontend] Implemented support for verifying diagnostics with the integrated frontend. Added a new DiagnosticOptions class to swiftBasic, and added a DiagnosticOptions member to CompilerInvocation. Added a static ParseDiagnosticArgs function to parse diagnostic-related arguments. Added -verify to FrontendOptions.td, and added support for parsing -verify in ParseDiagnosticArgs. Updated frontend_main() to enable and trigger the DiagnosticVerifier when -verify is passed. Swift SVN r11318
