Detailed Description

template<StubsFlavor Flavor>
class llvm::jitlink::aarch32::StubsManager< Flavor >

Stubs builder for a specific StubsFlavor.

Right now we only have one default stub kind, but we want to extend this and allow creation of specific kinds in the future (e.g. branch range extension or interworking).

Let's keep it simple for the moment and not wire this through a GOT.
