This change to reflect MLIR's recent addition to LLVM's monorepo. Instead of stripping llvm from the http archive, use build file map to refer to both MLIR and LLVM within llvm-project and remove read-only copy that was temporarily there. Also bump the commit version until after the integration of MLIR into LLVM monorepo. PiperOrigin-RevId: 287547194 Change-Id: I4459b96702dc5eb19b58c7ceaa6cabb16f530a43
