Improve debugging experience for enums on windows-msvc

This PR makes significant improvements over the status quo of debugging enums on the windows-msvc platform with either WinDbg or Visual Studio in three ways:

1. Improves the debugger experience for directly tagged enums.
2. Fixes a bug which caused the debugger to sometimes show the wrong debug info for niche layout enums. For example, `Option<&u32>` could sometimes use the debug info for `Option<&f64>` instead leading to nonsensical variable values in the debugger.
3. Significantly improves the debugger experience for niche-layout enums.

Let's look at a few examples:

```rust
pub enum CStyleEnum {
    Base = 2,
    Exponent = 16,
}

pub enum NicheLayoutEnum {
    Tag1,
    Data { my_data: CStyleEnum },
    Tag2,
    Tag3,
    Tag4,
}

pub enum OtherEnum<T> {
    Case1(T),
    Case2(T),
}

fn main() {
    let a = Some(CStyleEnum::Base);
    let b = Option::<CStyleEnum>::None;
    let c = NicheLayoutEnum::Tag1;
    let d = NicheLayoutEnum::Data { my_data: CStyleEnum::Exponent };
    let e = NicheLayoutEnum::Tag2;
    let f = Some(&1u32);
    let g = Option::<&'static u32>::None;
    let h = Some(&2u64);
    let i = Option::<&'static u64>::None;
    let j = Some(12u32);
    let k = Option::<u32>::None;
    let l = Some(12.34f64);
    let m = Option::<f64>::None;
    let n = CStyleEnum::Base;
    let o = CStyleEnum::Exponent;
    let p = Some("IAMA optional string!".to_string());
    let q = OtherEnum::Case1(42u32);
}
```

This is what WinDbg Preview shows using the latest rustc nightly:

Most of the variables don't show a meaningful value expect for a few cases that we have targeted natvis definitions covering. Even worse, drilling into many of these variables shows information that can be difficult to interpret without an understanding of the layout of Rust types:

With the changes in this PR, we're able to write two natvis definitions that cover all enum cases generally. After building with these changes, WinDbg now shows this instead:

Drilling into the same variables, we can see much more useful information:

rustc: Allow safe #[target_feature] on wasm

This commit updates the compiler's handling of the `#[target_feature]`
attribute when applied to functions on WebAssembly-based targets. The
compiler in general requires that any functions with `#[target_feature]`
are marked as `unsafe` as well, but this commit relaxes the restriction
for WebAssembly targets where the attribute can be applied to safe
functions as well.

The reason this is done is that the motivation for this feature of the
compiler is not applicable for WebAssembly targets. In general the
`#[target_feature]` attribute is used to enhance target CPU features
enabled beyond the basic level for the rest of the compilation. If done
improperly this means that your program could execute an instruction
that the CPU you happen to be running on does not understand. This is
considered undefined behavior where it is unknown what will happen (e.g.
it's not a deterministic `SIGILL`).

For WebAssembly, however, the target is different. It is not possible
for a running WebAssembly program to execute an instruction that the
engine does not understand. If this were the case then the program would
not have validated in the first place and would not run at all. Even if
this were allowed in some hypothetical future where engines have some
form of runtime feature detection (which they do not right now) any
implementation of such a feature would generate a trap if a module
attempts to execute an instruction the module does not understand. This
deterministic trap behavior would still not fall into the category of
undefined behavior because the trap is deterministic.

For these reasons the `#[target_feature]` attribute is now allowed on
safe functions, but only for WebAssembly targets. This notably enables
the wasm-SIMD intrinsics proposed for stabilization in #74372 to be
marked as safe generally instead of today where they're all `unsafe` due
to the historical implementation of `#[target_feature]` in the compiler.

Wesley Wiser [Thu, 13 May 2021 20:39:19 +0000 (16:39 -0400)]
Generate better debuginfo for niche-layout enums

Previously, we would generate a single struct with the layout of the
dataful variant plus an extra field whose name contained the value of
the niche (this would only really work for things like `Option<&_>`
where we can determine that the `None` case maps to `0` but for enums
that have multiple tag only variants, this doesn't work).

Now, we generate a union of two structs, one which is the layout of the
dataful variant and one which just has a way of reading the
discriminant. We also generate an enum which maps the discriminant value
to the tag only variants.

We also encode information about the range of values which correspond to
the dataful variant in the type name and then use natvis to determine
which union field we should display to the user.

As a result of this change, all niche-layout enums render correctly in
WinDbg and Visual Studio!

Don't sort a `Vec` before computing its `DepTrackingHash`

Previously, we sorted the vec prior to hashing, making the hash
independent of the original (command-line argument) order. However, the
original vec was still always kept in the original order, so we were
relying on the rest of the compiler always working with it in an
'order-independent' way.

This assumption was not being upheld by the `native_libraries` query -
the order of the entires in its result depends on the order of entries
in `Options.libs`. This lead to an 'unstable fingerprint' ICE when the
`-l` arguments were re-ordered.

This PR removes the sorting logic entirely. Re-ordering command-line
arguments (without adding/removing/changing any arguments) seems like a
really niche use case, and correctly optimizing for it would require
additional work. By always hashing arguments in their original order, we
can entirely avoid a cause of 'unstable fingerprint' errors.
