5e3b36c100 Fix code review actions in PR #32053
Split `fileline_note` into a `file_line note` and `span_suggestion` as per
@Manishearth's suggestions.

Change nested `match`es to `if let`s.

2dd5776b11 Add note if method is called on a function object
Fixes issue #29124.

If method is called on a function type a note is generated to suggest
that the developer may have forgotten to call it.

e.g.

fn main() {
    let mut guess = String::new();
    std::io::stdin.read_line(&mut guess);
}

will generate the note:

note: called method on function type. did you mean `std::io::stdin().read_line(..)`?

835d2a952c Rollup merge of #32342 - petevine:patch-1, r=alexcrichton
Use explicit -march flags in the i586 mk file

`-march` should definitely go last, after the environment `$C(XX)FLAGS`, or it's going to remain brittle.

This should fix cross-compilation issues on x86_64 (possibly x86 too on some newer distros) - it was far too assuming of me to expect you really had to want i586 using your own flags.

Add intrinsics for float arithmetic with `fast` flag enabled

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 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 that the
floats must be added in a sequence, one after another. This constraint
is usually completely unintended, and it means that no auto-vectorization
is possible.

derive: Avoid emitting provided PartialEq, PartialOrd methods for c-like enums

derive: Avoid emitting provided PartialEq, PartialOrd method for c-like enums

`ne` is completely symmetrical with the method `eq`, and we can save
rust code size and compilation time here if we only emit one of them
when possible.

One case where it's easy to recognize is when it's a C-like enum. Most
other cases can not omit ne, because any value field may have a custom
PartialEq implementation.

bca07b5ebb make suggestion stuff not swallow errors
The older code would sometimes swallow errors or fail to produce a
suggestion. The newer code does not. However, just printing everything
would produce a bunch of new and kind of annoying errors, so continue
to swallow `T: 'a` errors so long as there are other things to show.

Adjustments to the panic hook API

Rename `set_handler` and `take_handler` to `set_hook` and `take_hook` since we're not actually "handling" (i.e. fixing) anything.

Also alter `set_hook` to take a `Box<Fn(&PanicInfo) + 'static + Sync + Send>` rather than a parameterized closure since there's otherwise no easy way to re-register a hook that came from `take_hook`.
