Move ErrorReported to rustc_errors
The new location is more consistent with what this type is for, though we don't remove it from the old location (via a re-export) to avoid changing the dozens of use sites (~139 at this time).
Store pointer width as u32 on Config
This removes the dependency on IntTy, UintTy from Session.
It's not obviously a win, but it seems a bit odd to store the AST IntTy/UintTy in Session, rather we store the pointer width as an integer and add normalization methods to IntTy and UintTy.
tidy: Accommodate rustfmt's preferred layout of stability attributes
Previously tidy would require that the `feature = "name_of_feature"` part of the stability attribute was on the same line as the `#[stable(` / `#[unstable(` opening part of the attribute, and that `)]` was on the same line as the last key-value pair.
That didn't work with rustfmt's preferred layout of long attributes, which is like:
```rust
#[unstable(
feature = "c_variadic",
reason = "the `c_variadic` feature has not been properly tested on \
all supported platforms",
issue = "44930"
)]
```
introduce a target to build the kernel of the unikernel HermitCore
We are developing the unikernel HermitCore, where the kernel is written in Rust and is already supported by the Rust Standard Library. To compile the kernel with the new build flag "-Z build-std", we introduce a new target, which avoids the usage of SSE & AVX within the kernel.
Miri: print leak report even without tracing
Currently, the rustup-installed Miri has no way to actually print a leak report (as `trace!` is compiled out). Make it print that per default instead when there is a leak.

Add riscv64gc-unknown-linux-gnu target
This PR add the target, but doesn't build std on CI yet.
I have a port for `libc` crate and std which I will upstream soon after this target is added.

alloc: Add new_zeroed() versions like new_uninit().
MaybeUninit has both uninit() and zeroed(), it seems reasonable to have the same
surface on Box/Rc/Arc.
Needs tests.
cc #63291
Previously, only Self, &Self, &mut Self, Arc<Self>, Rc<Self>,
and Box<Self> were available as stable method receivers.
This commit stabilizes nested uses of all the above types.
However, nested receivers remain non-object-safe.
Add additional regression tests for PGO
This PR adds regression tests for making sure that
- instrumentation records the right counts for branches taken and functions called, and that
- the indirect call promotion pass actually is able to promote indirect calls.

Add support for sanitizer recover and tracking origins of uninitialized memory
* Add support for sanitizer recovery `-Zsanitizer-recover=...` (equivalent to `-fsanitize-recover` in clang).
* Add support for tracking origins of uninitialized memory in MemorySanitizer `-Zsanitizer-memory-track-origins` (equivalent to `-fsanitize-memory-track-origins` in clang).
Fix opaque types resulting from projections in function signature
When we normalize the types in a function signature, we may end up
resolving a projection to an opaque type (e.g. `Self::MyType` when
we have `type MyType = impl SomeTrait`). When the projection is
resolved, we will instantiate the generic parameters into fresh
inference variables.
While we do want to normalize projections to opaque types, we don't want
to replace the explicit generic parameters (e.g. `T` in `impl
MyTrait<T>`) with inference variables. We want the opaque type in the
function signature to be eligible to be a defining use of that opaque
type - adding inference variables prevents this, since the opaque type
substs now appears to refer to some specific type, rather than a generic
type.
To resolve this issue, we inspect the opaque types in the function
signature after normalization. Any inference variables in the substs are
replaced with the corresponding generic parameter in the identity substs
(e.g. `T` in `impl MyTrait<T>`). Note that normalization is the only way
that we can end up with inference variables in opaque substs in a
function signature - users have no way of getting inference variables
into a function signature.
Note that all of this refers to the opaque type (ty::Opaque) and its
subst - *not* to the underlying type.
