<pre>Simple testcase:
void foo() {}
__asm__(".symver foo,bar@@VER");
Run through clang and then opt -internalize -internalize-public-api-list=bar,
the 'foo' function is deleted but the .symver is retained.
Either the .symver should be deleted as well, or the symbol should be kept
alive (because the versioned symbol 'bar' is part of the declared public API).
Removing one but not the other breaks the IR and results in:
fatal error: error in backend: A @@ version cannot be undefined</pre>
