RISCVMachineFunctionInfo has some fields like VarArgsFrameIndex and VarArgsSaveSize are calculated at ISel lowering stage, those info are not contained in MIR files, that cause test cases rely on those field can't not reproduce correctly by MIR dump files. This patch adding the MIR read/write for those fields. Reviewed By: frasercrmck Differential Revision: https://reviews.llvm.org/D123178
