dcb64b52a2 represent fat ptr operands as 2 separate pointers
this does add some complexity, but to do otherwise would require unsized
lvalues to have their own allocas, which would be ugly.

602cf7ec3c MIR: implement fat raw pointer comparisons
The implementation itself only requires changes to trans, but
a few additional bugs concerning the handling of fat pointers
had to be fixed.

a0e10b249e Clean up some "suspicious" whitespace in target.mk
Emacs warns that makefile lines that start with spaces followed by
tabs are "suspicious".  These were harmless since they were
continuation lines, but getting rid of the warning is nice and this
version looks better.

876c33051a Escape some variables in llvm.mk
The important one is $(MAKE).  make handles recipes containing the
literal string "$(MAKE)" specially, so it is important to make sure it
isn't evaluated until recipe invocation time.

ec8ae4b0eb Auto merge of #29811 - bluss:binary-heap-sift-less, r=gankro
BinaryHeap: Simplify sift down

Sift down was doing all too much work: it can stop directly when the
current element obeys the heap property in relation to its children.

In the old code, sift down didn't compare the element to sift down at
all, so it was maximally sifted down and relied on the sift up call to
put it in the correct location.

This should speed up heapify and .pop().

Also rename Hole::removed() to Hole::element()

8a813e088c Auto merge of #29675 - bluss:merge-sort-fastpath, r=huonw
sort: Fast path for already sorted data

When merging two sorted blocks `left` and `right` if the last element in
`left` is <= the first in `right`, the blocks are already in sorted order.

Add this as an additional fast path by simply copying the whole left
block into the output and advancing the left pointer. The right block is
then treated the same way by the already present logic in the merge
loop.

Can reduce runtime of .sort() to less than 50% of the previous, if the data
was already perfectly sorted. Sorted data with a few swaps are also
sorted quicker than before. The overhead of one comparison per merge
seems to be negligible.

5a872880bd Auto merge of #29780 - KyleMayes:quote-ext, r=nrc
This is my first code contribution to Rust, so I'm sure there are some issues with the changes I've made.

I've added the `quote_arg!`, `quote_block!`, `quote_path!`, and `quote_meta_item!` quasiquoting macros. From my experience trying to build AST in compiler plugins, I would like to be able to build any AST piece with a quasiquoting macro (e.g., `quote_struct_field!` or `quote_variant!`) and then use those AST pieces in other quasiquoting macros, but this pull request just adds some of the low-hanging fruit.

I'm not sure if these additions are desirable, and I'm sure these macros can be implemented in an external crate if not.

8c9c9513cf Auto merge of #29544 - Ryman:reduce_doc_warnings, r=steveklabnik
Did this alphabetically, so I didn't see [how `std` was doing things](https://dxr.mozilla.org/rust/source/src/libstd/lib.rs#215) till I was nearly finished. If you prefer to add crate-level-whitelists like std instead of test-level, I can rebase with that strategy.

A number of these commits can probably be dropped as the crates don't have much to test, and are deprecated. Let me know which if any to drop! (can also squash after review if desired)

0bd708461b Auto merge of #29770 - ollie27:assert_eq_unsized, r=alexcrichton
`format_args!` doesn't support none Sized types so we should just pass it the references to `left_val` and `right_val`.

The following works:
```rust
assert!([1, 2, 3][..] == vec![1, 2, 3][..])
```
So I would expect this to as well:
```rust
assert_eq!([1, 2, 3][..], vec![1, 2, 3][..])
```
But it fails with "error: the trait `core::marker::Sized` is not implemented for the type `[_]` [E0277]"
I don't know if this change will have any nasty side effects I don't understand.

This mostly brings them in line with existing linking convention, but
also has some minor re-wording.

The text at the top has been re-focused, by starting out with what the
prelude does, rather than starting from injecting std.

Also, it now mentions that other preludes exist.

b7f6d7239b Rollup merge of #29776 - nikomatsakis:mir-29740, r=nrc
In previous PRs, I changed the match desugaring to generate more efficient code for ints/chars and the like. But this doesn't help when you're matching strings, ranges, or other crazy complex things (leading to #29740). This commit restructures match desugaring *yet again* to handle that case better -- basically we now degenerate to an if-else-if chain in such cases.

~~Note that this builds on https://github.com/rust-lang/rust/pull/29763 which will hopefully land soon. So ignore the first few commits.~~ landed now
