Regression test for #132395, after I was able to figure out a simple way to reproduce it. See also #132436.

In addition to confirming that there is no ICE, this test also demonstrates that the affected code is undercounted, because executing the inlined copy doesn't increment coverage counters.

Whether or not running this program produces a .profraw file appears to vary by platform.

Since that isn't the main point of this test, I've just added //@ ignore-coverage-run as a workaround (diff).

I'm also running a side job to verify that the fix actually works.
