Subject: cmd/compile: add test for Issue 12536
X-Git-Tag: go1.9beta1~682

cmd/compile: add test for Issue 12536

The fixedbugs/issue12536.go file was erroneously deleted just before
committing the patch that fixed the issue (CL 14400).

That's an easy test and there's a small reproducer in the issue, add
it back.

Updates #12536
