Split Text.LLVM.AST into Data.LLVM.IR and Data.LLVM.IR.Textual?

[angerman]

The AST is used in the llvm-pretty-bc-parser as well, and could be useful on it's own, would it hurt to split Text.LLVM.AST into the IR data representations (Data.LLVM.IR) and the textual pretty printer (Data.LLVM.IR.Textual)?

That would allow to just import the IR.
