Jamie Cunliffe a059e68d11 Create a structure to define the features from to_llvm_features.
Rather than returning an array of features from to_llvm_features, return a structure that contains
the dependencies. This also contains metadata on how the features depend on each other to allow for
the correct enabling and disabling.
