The goal of this patch is to list the supported extensions and their versions by providing an option, so I guess `clang/test/Driver/print-supported-extensions.c` aims differently with `llvm/unittests/Support/RISCVISAInfoTest.cpp` which is testing the functionalities in `RISCVISAInfoTest.cpp`.
`clang/test/Driver/print-supported-extensions.c` only tracks the extensions added and the their version changes and `riscvExtensionsHelp` in `llvm/lib/Support/RISCVISAInfo.cpp` doesn't have any input or output as well as any side effect, it only reads `SupportedExtensions` and `SupportedExperimentalExtensions` and dump the information.
So I think `clang/test/Driver/print-supported-extensions.c` is enough for this patch?
