auto merge of #20060 : Aatch/rust/enum-repr, r=alexcrichton
The previous behaviour of using the smallest type possible caused LLVM to treat padding too conservatively, causing poor codegen. This commit changes the behaviour to use an alignment-sized integer as the discriminant. This keeps types the same size, but helps LLVM understand the data structure a little better, resulting in better codegen.
