Automated conversion using the untry tool [1] and the following command:

```
$ find -name '*.rs' -type f | xargs untry
```

e3f2dfdece Auto merge of #32156 - pnkfelix:borrowck-on-mir-move-analysis, r=nikomatsakis
Move analysis for MIR borrowck

This PR adds code for doing MIR-based gathering of the moves in a `fn` and the dataflow to determine where uninitialized locations flow to, analogous to how the same thing is done in `borrowck`.

It also adds a couple attributes to print out graphviz visualizations of the analyzed MIR that includes the dataflow analysis results.

8eeb5062d1 Auto merge of #32244 - Amanieu:compare_exchange_result, r=alexcrichton
Change compare_exchange to return a Result<T, T>

As per the discussion in #31767

I also changed the feature name from `extended_compare_and_swap` to `compare_exchange`.

2dbac1fb8e Add intrinsics for float arithmetic with fast flag enabled
`fast` a.k.a UnsafeAlgebra is the flag for enabling all "unsafe"
(according to llvm) float optimizations.

See LangRef for more information http://llvm.org/docs/LangRef.html#fast-math-flags

Providing these operations with less precise associativity rules (for
example) is useful to numerical applications.

For example, the summation loop:

    let sum = 0.;
    for element in data {
        sum += *element;
    }

Using the default floating point semantics, this loop expresses the
floats must be added in a sequence, one after another. This constraint
is usually completely unintended, and it means that no autovectorization
is possible.
