"Standard-to-LLVM" conversion is one of the oldest passes in existence. It has become quite large due to the size of the Standard dialect itself, which is being split into multiple smaller dialects. Furthermore, several conversion features are useful for any dialect that is being converted to the LLVM dialect, which, without this refactoring, creates a dependency from those conversions to the "standard-to-llvm" one. Put several of the reusable utilities from this conversion to a separate library, namely: - type converter from builtin to LLVM dialect types; - utility for building and accessing values of LLVM structure type; - utility for building and accessing values that represent memref in the LLVM dialect; - lowering options applicable everywhere. Additionally, remove the type wrapping/unwrapping notion from the type converter that is no longer relevant since LLVM types has been reimplemented as first-class MLIR types.
