[LLVMdev] RFC: Could we move TargetLibraryInfo into lib/Analysis?

[Chandler Carruth]

While this is target information, it isn't actually part of the target
today and doesn't use any part of the target code. Maybe some day we can
use a target hook to initialize the data structures, but even then I feel
like this really belongs in the core analysis library.

Would there be any objections to just moving it into Analysis?

Doing this would remove a seriously ugly layering violation we have today.
I believe this would remove the last dependency on lib/Target by
lib/Analysis and the largest set of dependencies on lib/Target by
lib/Transforms.

If there is general agreement, I will make it so.
