dde7283b80 Auto merge of #28651 - dotdash:exhaustive_match, r=eddyb 
By putting an "unreachable" instruction into the default arm of a switch
instruction we can let LLVM know that the match is exhaustive, allowing
for better optimizations.

For example, this match:
```rust
pub enum Enum {
    One,
    Two,
    Three,
}

impl Enum {
    pub fn get_disc(self) -> u8 {
        match self {
            Enum::One => 0,
            Enum::Two => 1,
            Enum::Three => 2,
        }
    }
}
```

Currently compiles to this on x86_64:
```asm
  .cfi_startproc
  movzbl  %dil, %ecx
  cmpl  $1, %ecx
  setne %al
  testb %cl, %cl
  je  .LBB0_2
  incb  %al
  movb  %al, %dil
.LBB0_2:
  movb  %dil, %al
  retq
.Lfunc_end0:
```

But with this change we get:
```asm
  .cfi_startproc
  movb  %dil, %al
  retq
.Lfunc_end0:
```

2e88c36ebc Auto merge of #28642 - petrochenkov:name3, r=nrc 
This PR removes random remaining `Ident`s outside of libsyntax and performs general cleanup
In particular, interfaces of `Name` and `Ident` are tidied up, `Name`s and `Ident`s being small `Copy` aggregates are always passed to functions by value, and `Ident`s are never used as keys in maps, because `Ident` comparisons are tricky.

Although this PR closes https://github.com/rust-lang/rust/issues/6993 there's still work related to it:
- `Name` can be made `NonZero` to compress numerous `Option<Name>`s and `Option<Ident>`s but it requires const unsafe functions.
- Implementation of `PartialEq` on `Ident` should be eliminated and replaced with explicit hygienic, non-hygienic or member-wise comparisons.
- Finally, large parts of AST can potentially be converted to `Name`s in the same way as HIR to clearly separate identifiers used in hygienic and non-hygienic contexts.

f17cc4cf04 Auto merge of #28578 - gandro:nodefaultlibs, r=alexcrichton 
This patch basically adds a target option for omitting the `-nodefaultlibs` flag when invoking the linker. I am not sure if this is the correct or only way to approach this problem, so any feedback is welcome.

Motivation: I'm currently working on a Rust target specification for the [rumprun](/rumpkernel/rumprun) unikernel. rumprun is based on rump kernels and uses NetBSDs libc and drivers to provide a POSIXy environment. It provides its own linker wrapper that generates binaries which can be "baked" into a unikernel after configuration. Using `-nodefaultlibs` on the rumprun linker will prevent it from selecting the search paths for the rumprun libraries. My current target implementation for rumprun is here: gandro/rust@295744b2ee

Currently, only a target that `is_like_windows` will omit the `-nodefaultlibs` flag, but since rumprun is not like Windows otherwise, I think a separate flag makes more sense. This might be a breaking change for target specifications that have the `is_like_windows` option set to true. Such targets need to set `no_default_libraries` to false in order to restore the old behavior.

920f32becd Add no_default_libraries target linker option 
If set to false, `-nodefaultlibs` is not passed to the linker. This
was the default behavior on Windows, but it should be configurable
per target.

This is a [breaking-change] for target specifications that have
the `is_like_windows` option set to true. Such targets need to
set `no_default_libraries` to false in order to restore the old
behavior.

66f662f37d Fix crash with --save-analysis 
Should be lowering ast expressions to HIR expressions, not cheating via the hir map. That goes wrong now that there is not a 1:1 mapping between ast and hir (in the case of the crash due to ExprParen).

e9f1b06329 Use ast attributes every where (remove HIR attributes). 
This could be a [breaking-change] if your lint or syntax extension (is that even possible?) uses HIR attributes or literals.

This allows to skip the codegen for all the unneeded landing pads, reducing code size across the board by about 2-5%, depending on the crate. Compile times seem to be pretty unaffected though :-/

3ef75d5774 Mark all extern functions as nounwind 
Unwinding across an FFI boundary is undefined behaviour, so we can mark
all external function as nounwind. The obvious exception are those
functions that actually perform the unwinding.
