Can I put in a plea to have as much of LLVM as possible *not* require
knowledge of a single, specific architecture to work?

I have various things I would like to do that work on abstract machines,
where I don't have a specific target or CPU in mind, but just want to
work at the bitcode level. Right now the only way I know of doing this
is to hardcode the datalayout into a new target and rebuild the whole
shooting match, LLVM and clang combined. I very much do not want to do this.

What would be really nice is to be able to specify a custom datalayout
on the command line and have as many tools as possible still work,
particularly clang --- trying to generate code with non-standard
datalayouts is kinda hard right now.
