I went into some detail on the time complexity of `push` because it is
relevant for using BinaryHeap efficiently -- specifically that you
should avoid pushing many elements in ascending order when possible.

Simplify BufRead::fill_buf doc example using NLL
With non-lexical lifetimes, in this example it is no longer necessary to use a block to end the borrow early.
Use iter() for iterating arrays by slice
These `into_iter()` calls will change from iterating references to
values if we ever get `IntoIterator` for arrays, which may break the
code using that iterator. Calling `iter()` is future proof.
Mark core::alloc::Layout::from_size_align_unchecked const
Makes it possible (pending stabilization of #57563 (`const_fn`)) to rewrite code like
```rust
const BUFFER_SIZE: usize = 0x2000;
const BUFFER_ALIGN: usize = 0x1000;
fn foo() {
let layout = std::alloc::Layout::from_size_align(BUFFER_SIZE, BUFFER_ALIGN)
.unwrap();
let buffer = std::alloc::alloc(layout);
}
```
to
```rust
const BUFFER_LAYOUT: std::alloc::Layout = unsafe {
std::alloc::Layout::from_size_align_unchecked(0x2000, 0x1000)
};
fn foo() {
let buffer = std::alloc::alloc(BUFFER_LAYOUT);
}
```
which (although `unsafe` is used) looks somewhat cleaner and is easier to read.
Added ignore-sgx for appropriate tests in src/test
These are all the tests that make sense to ignore when targeting fortanix-unknonw-sgx, at least in test/runpass. Other suites not yet covered.
These `into_iter()` calls will change from iterating references to
values if we ever get `IntoIterator` for arrays, which may break the
code using that iterator. Calling `iter()` is future proof.

implement #46205
r? @nikomatsakis
Prevent Error::type_id overrides
type_id now takes an argument that can't be named outside of the
std::error module, which prevents any implementations from overriding
it. It's a pretty grody solution, and there's no way we can stabilize
the method with this API, but it avoids the soudness issue!
Closes#60784

Update the compiler_builtins crate
This updates to 0.1.13 for `compiler_builtins`, published to fix a few
issues. The feature changes here are updated because `compiler_builtins`
no longer enables the `c` feature by default but we want to do so
through our build still.
Closes#60747Closes#60782

Checking generic args after late bound region err.
Fixes#60622.
This PR fixes an ICE that occurs when a late bound region error is
emitted and that resulted in the rest of the generic arguments of a
function not being checked.
For example, you could specify a generic type parameter `T` in a function
call `foo<'_, T>()` to a function that doesn't have a generic type
parameter.
Since an error wasn't emitted from the function, compilation
continued to parts of typeck that didn't expect a generic type argument
in a call for a function that didn't have any generic type arguments.
