Fixes PR 31921 Summary: Predicateinfo requires an ugly workaround to try to avoid literal struct types due to the intrinsic mangling not being implemented. This workaround actually does not work in all cases (you can hit the assert by bootstrapping with -print-predicateinfo), and can't be made to work without DFS'ing the type (IE copying getMangledStr and using a version that detects if it would crash). Rather than do that, i just implemented the mangling. It seems simple, since they are unified structurally. Looking at the overloaded-mangling testcase we have, it actually turns out the gc intrinsics will *also* crash if you try to use a literal struct. Thus, the testcase added fails before this patch, and works after, without needing to resort to predicateinfo.
