954873055a Auto merge of #36823 - durka:discriminant_value, r=nagisa
add wrapper for discriminant_value, take 2

[This is #34785 reopened, since @bors apparently gave up on that thread.]

add wrapper for discriminant_value intrinsic

Implementation of [RFC 1696](https://github.com/rust-lang/rfcs/blob/master/text/1696-discriminant.md).

Wraps the `discriminant_value` intrinsic under the name `std::mem::discriminant`. In order to avoid prematurely leaking information about the implementation of enums, the return value is an opaque type, generic over the enum type, which implements Copy, Clone, PartialEq, Eq, Hash, and Debug (notably not PartialOrd). There is currently no way to get the value out excepting printing the debug representation.

The wrapper is safe and can be stabilized soon as per discussion in #24263.

Move MIR towards a single kind of local

This PR modifies MIR to handle function arguments (`Arg`), user-defined variable bindings (`Var`), compiler-generated temporaries (`Tmp`), as well as the return value pointer equally. All of them are replaced with a single `Local` type, a few functions for iterating over different kinds of locals, and a way to get the kind of local we're dealing with (mainly used in the constant qualification/propagation passes).

~~I haven't managed to fix one remaining issue: A `StorageDead` not getting emitted for a variable (see the `TODO` in the test). If that's fixed, this is basically good to go.~~ Found the issue (an off-by-one error), fix incoming.

dd13a80344 impl {Add, AddAssign}<{str, Cow<str>}> for Cow<str>
This does not actually add anything that wasn't there, but is merely an
optimization for the given cases, which would have incurred additional
heap allocation for adding empty strings, and improving the ergonomics
of `Cow` with strings.

9143c3c9c0 Rollup merge of #36794 - japaric:target-panic, r=alexcrichton
add a panic-strategy field to the target specification

Now a target can define its panic strategy in its specification. If a
user doesn't specify a panic strategy via the command line, i.e. '-C
panic', then the compiler will use the panic strategy defined by the
target specification.

Custom targets can pick their panic strategy via the "panic-strategy"
field of their target specification JSON file. If omitted in the
specification, the strategy defaults to "unwind".

closes #36647

---

I checked that compiling an executable for a custom target with "panic-strategy" set to "abort" doesn't need the "eh_personality" lang item and also that standard crates compiled for that custom target didn't contained undefined symbols to _Unwind_Resume. But this needs an actual unit test, any suggestion on how to test this?

Most of the noise in the diff is due to moving `PanicStrategy` from the `rustc` to the `rustc_back` crate.

f1ea5cc273 Rollup merge of #36789 - jseyfried:non_inline_mod_in_block, r=nikomatsakis
Allow more non-inline modules in blocks

Currently, non-inline modules without a `#[path]` attribute are not allowed in blocks.
This PR allows non-inline modules that have an ancestor module with a `#[path]` attribute, provided there is not a nearer ancestor block.

For example,
```rust
fn main() {
    #[path = "..."] mod foo {
        mod bar; //< allowed by this PR
        fn f() {
            mod bar; //< still an error
        }
    }
}
```

8f2c000506 Rollup merge of #36741 - matklad:no-flacky-test, r=alexcrichton
Remove CString drop test.

The test relies on the undefined behavior, and so may fail in some
circumstances. This can be worked around by stubbing a memory allocator
in the test, but it is a bit of work, and LLVM could still theoretically
eliminate the write of the zero byte in release mode (which is
intended).

So let's just remove the test and mark the function as inline. It
shouldn't be optimized away when inlined into the debug build of user's
code.

Supersedes #36607

Move ty_align and ty_size out of most C ABI code

s390x's C ABI ty_align and ty_size are not moved because the
implementation of ty_align varies in an atypical pattern: it calls
ty_size for the llvm::Vector type kind. ty_size then cannot be moved
since it indirectly calls ty_align through align.
