This was left over from when closure copy and clone were gated behind feature flags.
Here, ExprKind::Use(P<Expr>) tweaks the drop order to act the
same way as '{ let _tmp = expr; _tmp }' does.

Add Pin::{into_inner,into_inner_unchecked}
These functions are useful for unsafe code that needs to temporarily pull smart pointers out of the `Pin`, e.g. [the change that inspired them](Nemo157/futures-rs@b436178#diff-1a4e0ba4d1b539412ca576411ec6c7c2R258) is taking a `Pin<Box<dyn Future>>`, turning it into a `*mut dyn Future` via `Box::into_raw(unsafe { Pin::into_inner_unchecked(pin) })` then later dropping this via `drop(Pin::from(Box::from_raw(ptr)))`. This can be accomplished today via `{ let ptr = unsafe { Pin::get_unchecked_mut(pin.as_mut()) } as *mut dyn Future; mem::forget(pin); ptr }`, but this is far more complicated and loses out on the symmetry of using `Box::into_raw` and `Box::from_raw`.
I'll extend the documentation on what guarantees `into_inner_unchecked` needs to uphold once I get some feedback on whether this API is wanted or not.

Introduce hir::ExprKind::Use and employ in for loop desugaring.
In the `for $pat in $expr $block` desugaring we end with a `{ let _result = $match_expr; _result }` construct which makes `for` loops into a terminating scope and affects drop order. The construct was introduced in year 2015 by @pnkfelix in rust-lang#21984.
This PR replaces the construct with `hir::ExprKind::Use(P<hir::Expr>)` which is equivalent semantically but should hopefully be less costly in terms of compile time performance (to be determined).
This is extracted out of rust-lang@91b0abd from rust-lang#59288 for easier review and so that the perf implications wrt. `for`-loops can be measured.

…ss, r=alexcrichton PGO: Add a run-make test that makes sure that PGO profiling data is used by the compiler during optimizations. From the tests comment section: ``` # This test makes sure that PGO profiling data leads to cold functions being # marked as `cold` and hot functions with `inlinehint`. # The test program contains an `if` were actual execution only ever takes the # `else` branch. Accordingly, we expect the function that is never called to # be marked as cold. ``` r? @alexcrichton
