I just move RISCVExtensionVersion structure here, and remove RISCVExtensionInfo structure.
I think that RISCVExtensionInfo is redundant.


================
Comment at: llvm/lib/Support/RISCVISAInfo.cpp:190
+                                RISCVExtensionVersion Version) {
+  assert(!Exts.count(ExtName.str()) && "Extension already exists");
+  Exts[ExtName.str()] = Version;
