[PATCH] D158050: [RISCV] RISCV vector calling convention (2/2)

[Brandon Wu via Phabricator via llvm-commits]

4vtomat added a comment.

`RVVArgDispatcher` is the class used to compute and maximize the register usage by using the vector argument information placed in `std::vector<RVVArgInfo>`, it's both used by `frontend` and `backend`.
Currently I'm not sure where is the better file to place this class, so I just place it in `RISCVTargetParser.h`.
