Rollup merge of #119759 - sfzhu93:master, r=cjgillot 
Add FileCheck annotations to dataflow-const-prop tests

part of #116971.

A few shadowing variable names are changed, so that it is easier to match the variable names in MIR using FileCheck syntax.

Also, there's a FIXME in [enum.rs](https://github.com/rust-lang/rust/pull/119759/files#diff-7621f55327838e489a95ac99ae1e6126b37c57aff582594e6bee9d7e7e56fc58) because the MIR looks suspicious to me. It has been explained in the comments.

Allow partially moved values in match

This PR attempts to unify the behaviour between `let _ = PLACE`, `let _: TY = PLACE;` and `match PLACE { _ => {} }`.
The logical conclusion is that the `match` version should not check for uninitialised places nor check that borrows are still live.

The `match PLACE {}` case is handled by keeping a `FakeRead` in the unreachable fallback case to verify that `PLACE` has a legal value.

Schematically, `match PLACE { arms }` in surface rust becomes in MIR:
```rust
PlaceMention(PLACE)
match PLACE {
  // Decision tree for the explicit arms
  arms,
  // An extra fallback arm
  _ => {
    FakeRead(ForMatchedPlace, PLACE);
    unreachable
  }
}
```

`match *borrow { _ => {} }` continues to check that `*borrow` is live, but does not read the value.
`match *borrow {}` both checks that `*borrow` is live, and fake-reads the value.
