The vscale_range is used for scalabale vector functionality in Arm Scalable Vector Extension to select the size of vector operation (and I thnk RISCV has something similar). This patch adds the base support for the vscale_range attribute to the LLVM::FuncOp, and the marshalling for translation to LLVM-IR and import from LLVM-IR to LLVM dialect. This attribute is intended to be used at higher level MLIR, specified either by command-line options to the compiler or using compiler directives (e.g. pragmas or function attributes in the source code) to indicate the desired range.
