[PATCH] D149342: [RISCV] Add test describing constant materialisation problem in loops

[Luke Lau via Phabricator via llvm-commits]

The cost model will probably need a bit of reworking, and I'm not sure if these constant materialisation costs will end up being factored out of `getInstructionCost` or if there will be some other interface, so these tests are not that useful as it stands.
