David Mo 4160337c85 Tests crash from inappropriate use of common linkage
Normally, variables with common linkage must be zero-initialized. In Rust,
common linkage variables that are not zero-initialized causes a crash in the
compiler backend.

This commit adds a test case to confirm this behavior, which will inform us if
it changes in the future.

// This test verifies that we continue to hit the LLVM error for common linkage with non-zero
// initializers, since it generates invalid LLVM IR.
// Linkages are internal features marked as perma-unstable, so we don't need to fix the issue
