stage2: Resolve union layout before getting tag type in zirTagname

This bug only causes a failure on my machine when running test/behavior/eval.zig directly. If running the full behavior test suite, std.builtin.TypeInfo will have already resolved its layout, causing the test to pass. I'd love to add a test that can reliably reproduce this problem, but I'm afraid I'm not sure how to reliably create a union with un-resolved layout.
