dianqk 630d55cce4 [AsmPrinter] Always emit global equivalents if there is non-global uses (#145648) ...

A case found from https://github.com/rust-lang/rust/issues/142752:
https://llvm.godbolt.org/z/T7ce9saWh.

We should emit `@bar_0` for the following code:

```llvm
target triple = "x86_64-unknown-linux-gnu"

@rel_0 = private unnamed_addr constant [1 x i32] [
  i32 trunc (i64 sub (i64 ptrtoint (ptr @bar_0 to i64), i64 ptrtoint (ptr @rel_0 to i64)) to i32)]
@bar_0 = internal unnamed_addr constant ptr @foo_0, align 8
@foo_0 = external global ptr, align 8

define void @foo(ptr %arg0) {
  store ptr @bar_0, ptr %arg0, align 8
  ret void
}
```
