Realized I missed this question on my first read through. This came up compiling the julia system image. We do generally also lower things to sret. However, for things like `Union{RegEx, Int64}`, we emit that as a tagged union `{jl_value_t *, i8}`, which doesn't get sret'ed, because ideally we'd like it in two registers.
