r246468 - Pull the target attribute parsing out of CGCall and onto TargetInfo.

[Hans Wennborg via cfe-commits]

This change makes Basic depend on AST.

The immediate problem I'm hitting is clang-format (which uses Basic
but not AST) failing to link on Windows [1], but I suspect this could
cause problems elsewhere too.

Is there some way to avoid this dependency?
