This patch makes -version valid, and --version invalid, for flang-new -fc1. The invocation flang-new --version remains valid. This behaviour is consistent with clang (and with clang -cc1 and clang -cc1as). Previously, flang-new -fc1 accepted --version (as per Options.td), but the frontend driver acutally checks for -version. As a result, flang-new -fc1 --version triggered no action, emitted no message, and stalled waiting for standard input.
