Some build configs allow `llvm_unreachable` in a constexpr context, but not all, so these functions that map a fully covered enum to a string can't be constexpr. This version fixes that by dropping constexpr from those functions. This reverts commit fcc318ff7960d7de8cbac56eb4f32b44b5261677, reapplying 28d577ecefa1557f5dea5566bf33b885c563d14b. Original message follows: This implements the DXILResourceAnalysis pass for `dx.TypedBuffer` and `dx.RawBuffer` types. This should be sufficient to lower `dx.handle.fromBinding` for this set of types, but it leaves a number of TODOs around for other resource types. This also includes a straightforward `print` method in `ResourceInfo` to make the analysis testable. This is deliberately different than the printer in `lib/Target/DirectX/DXILResource.cpp`, which attempts to print bindings in a format compatible with the comments `dxc` prints. We will eventually want to make that functionality driven by this analysis pass, but it isn't sufficient for testing so we need both.
