The types of statics, like all other items, are stored in the tcx
unnormalized. This is necessarily so, because
a) Item types other than statics have generics, which can't be
normalized.
b) Eager normalization causes undesirable on-demand dependencies.
Keeping with the principle that MIR lvalues require no normalization in
order to interpret, this patch stores the normalized type of the statics
in the Lvalue and reads it to get the lvalue type.
Fixes#39367.
The line '.expect("failed to read line");' is partly started with a
lower case 'f' and partly with an uppercase one, adding additional
spurious changes to otherwise clean diffs if each sample is
copy-and-pasted over the previous.
This change starts the string with an uppercase everywhere which is in
line with the style of the other strings.
Make transmuting from fn item types to pointer-sized types a hard error.
Closes#19925 by removing the future compatibility lint and the associated workarounds.
This is a `[breaking-change]` if you `transmute` from a function item without casting first.

Simplify `TokenTree` and fix `macro_rules!` bugs
This PR
- fixes#39390, fixes#39403, and fixes#39404 (each is a [breaking-change], see issues for examples),
- fixes#39889,
- simplifies and optimizes macro invocation parsing,
- cleans up `ext::tt::transcribe`,
- removes `tokenstream::TokenTree::Sequence` and `Token::MatchNt`,
- instead, adds a new type `ext::tt::quoted::TokenTree` for use by `macro_rules!` (`ext::tt`)
- removes `parser.quote_depth` and `parser.parsing_token_tree`, and
- removes `quote_matcher!`.
- Instead, use `quote_tokens!` and `ext::tt::quoted::parse` the result with `expect_matchers=true`.
- I found no outside uses of `quote_matcher!` when searching Rust code on Github.

Move two large error_reporting fn's to a separate file
Hello!
I tried to make `librustc/infer/error_reporting,rs` more readable by modularizing it and moving its two largest functions to a separate file.
If you have any suggestions, please send it right away! 🚀
Thanks goes to @nikomatsakis for supporting.
added Error and Display impl for std::ffi::FromBytesWithNulError
Fixes#39925.
This is my first PR, so I wasn't quite sure about the stability annotation.
impl RangeArgument for RangeInclusive and add appropriate tests
Now that `RangeArgument` returns a `Bound`, the impl for `RangeInclusive` is natural to implement and all that's required are tests around it.

sort unstable book alphabetically
I made these the same order as they were in the compiler, but for no good reason. Much easier to find out what you need when they're sorted alphabetically

Structs doc: Change "pointers" to "references"
Let's call them "references" instead of "pointers". That's how they're called in chapter 4.9 "References and Borrowing".
