Convert the TargetTransformInfo from an immutable pass with dynamic
interfaces which could be extracted from it, and must be provided on construction, to a chained analysis group. The end goal here is that TTI works much like AA -- there is a baseline "no-op" and target independent pass which is in the group, and each target can expose a target-specific pass in the group. These passes will naturally chain allowing each target-specific pass to delegate to the generic pass as needed. In particular, this will allow a much simpler interface for passes that would like to use TTI -- they can have a hard dependency on TTI and it will just be satisfied by the stub implementation when that is all that is available. This patch is a WIP however. In particular, the "stub" pass is actually the one and only pass, and everything there is implemented by delegating to the target-provided interfaces. As a consequence the tools still have to explicitly construct the pass. Switching targets to provide custom passes and sinking the stub behavior into the NoTTI pass is the next step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171621 91177308-0d34-0410-b5e6-96231b3b80d8
