C++98 and C++03 are effectively aliases as far as Clang is concerned. As such, allowing both std=c++98 and std=c++03 as Lit parameters is just slightly confusing, but provides no value. It's similar to allowing both std=c++17 and std=c++1z, which we don't do. This was discovered because we had an internal bot that ran the test suite under both c++98 AND c++03 -- one of which is redundant. Differential Revision: https://reviews.llvm.org/D80926
