[clang-cl] Provide separate flags for all the /O variants This provides better help text in "clang-cl /?". Also it cleans things up a bit: previously "/Od" could be handled either as a separate flag aliased to "-O0", or by the main optimization flag processing in TranslateOptArg. With this patch, all the flags get aliased back to /O so they're handled by TranslateOptArg. Thanks to Nico for the idea! Differential revision: https://reviews.llvm.org/D52266 llvm-svn: 342977
