Fix IRGen for passing transparent unions
...
We have had a test for this for a long time with a FIXME saying what we
should be doing. This just does it.
Fixes PR21573.

fix an unintended behavior change in the type system rewrite, which caused us to compile
...
stuff like this:
typedef struct {
int x, y, z;
} foo_t;
foo_t g;
into:
%"struct.<anonymous>" = type { i32, i32, i32 }
we now get:
%struct.foo_t = type { i32, i32, i32 }
This doesn't change the behavior of the compiler, but makes the IR much easier to read.
