Enable PE verification in tests of unsafe code #23130
Description
Currently CompileAndVerify (src/Test/Utilities/Portable/CommonTestBase.cs, line 126) automatically skips PE verification if the compilation has unsafe flag. We should tighten this and identify individual tests for unsafe code that should skip PE verification.
if (verify)
{
// Unsafe code might not verify, so don't try.
var csharpOptions = compilation.Options as CSharp.CSharpCompilationOptions;
verify = (csharpOptions == null || !csharpOptions.AllowUnsafe);
