JSON file_name paths were changed in #66364 for macros to point to actual source files instead of using <MACRONAME macros>.

Closes #70396

Pkgsrc changes:
 * Remove a couple diffs which are now integrated upstream.
 * Adjust cargo checksums after upstream upgrades.
 * Belatedly bump the curl dependency
 * Unset DESTDIR during the build phase, to work around a mysterious
   build bug deep in the bowels of llvm.
 * Bump nearly all bootstraps to 1.43.1.

Upstream changes:

Version 1.44.0 (2020-06-04)
==========================

Language
--------
- [You can now use `async/.await` with `#[no_std]` enabled.][69033]
- [Added the `unused_braces` lint.][70081]

**Syntax-only changes**

- [Expansion-driven outline module parsing][69838]
```rust
#[cfg(FALSE)]
mod foo {
    mod bar {
        mod baz; // `foo/bar/baz.rs` doesn't exist, but no error!
    }
}
```

These are still rejected semantically, so you will likely receive an error but
these changes can be seen and parsed by macros and conditional compilation.

Compiler
--------
- [Rustc now respects the `-C codegen-units` flag in incremental mode.][70156]
  Additionally when in incremental mode rustc defaults to 256 codegen units.
- [Refactored `catch_unwind`, to have zero-cost unless unwinding is enabled and
  a panic is thrown.][67502]
- [Added tier 3\* support for the `aarch64-unknown-none` and
  `aarch64-unknown-none-softfloat` targets.][68334]
- [Added tier 3 support for `arm64-apple-tvos` and
  `x86_64-apple-tvos` targets.][68191]

Libraries
---------
- [Special cased `vec![]` to map directly to `Vec::new()`.][70632] This allows
  `vec![]` to be able to be used in `const` contexts.
- [`convert::Infallible` now implements `Hash`.][70281]
- [`OsString` now implements `DerefMut` and `IndexMut` returning
  a `&mut OsStr`.][70048]
- [Unicode 13 is now supported.][69929]
- [`String` now implements `From<&mut str>`.][69661]
- [`IoSlice` now implements `Copy`.][69403]
- [`Vec<T>` now implements `From<[T; N]>`.][68692] Where `N` is less than 32.
- [`proc_macro::LexError` now implements `fmt::Display` and `Error`.][68899]
- [`from_le_bytes`, `to_le_bytes`, `from_be_bytes`, `to_be_bytes`,
  `from_ne_bytes`, and `to_ne_bytes` methods are now `const` for all
  integer types.][69373]

Stabilized APIs
---------------
- [`PathBuf::with_capacity`]
- [`PathBuf::capacity`]
- [`PathBuf::clear`]
- [`PathBuf::reserve`]
- [`PathBuf::reserve_exact`]
- [`PathBuf::shrink_to_fit`]
- [`f32::to_int_unchecked`]
- [`f64::to_int_unchecked`]
- [`Layout::align_to`]
- [`Layout::pad_to_align`]
- [`Layout::array`]
- [`Layout::extend`]

Cargo
-----
- [Added the `cargo tree` command which will print a tree graph of
  your dependencies.][cargo/8062] E.g.
  ```
    mdbook v0.3.2 (/Users/src/rust/mdbook)
  +-- ammonia v3.0.0
  |   +-- html5ever v0.24.0
  |   |   +-- log v0.4.8
  |   |   |   +-- cfg-if v0.1.9
  |   |   +-- mac v0.1.1
  |   |   +-- markup5ever v0.9.0
  |   |       +-- log v0.4.8 (*)
  |   |       +-- phf v0.7.24
  |   |       |   +-- phf_shared v0.7.24
  |   |       |       +-- siphasher v0.2.3
  |   |       |       +-- unicase v1.4.2
  |   |       |           [build-dependencies]
  |   |       |           +-- version_check v0.1.5
  ...
  ```
  You can also display dependencies on multiple versions of the same crate with
  `cargo tree -d` (short for `cargo tree --duplicates`).

Misc
----
- [Rustdoc now allows you to specify `--crate-version` to have rustdoc include
  the version in the sidebar.][69494]

Compatibility Notes
-------------------
- [Rustc now correctly generates static libraries on Windows GNU targets with
  the `.a` extension, rather than the previous `.lib`.][70937]
- [Removed the `-C no_integrated_as` flag from rustc.][70345]
- [The `file_name` property in JSON output of macro errors now points the actual
  source file rather than the previous format of `<NAME macros>`.][70969]
  **Note:** this may not point a file that actually exists on the user's system.
- [The minimum required external LLVM version has been bumped to LLVM 8.][71147]
- [`mem::{zeroed, uninitialised}` will now panic when used with types that do
  not allow zero initialization such as `NonZeroU8`.][66059] This was
  previously a warning.
- [In 1.45.0 (the next release) converting a `f64` to `u32` using the `as`
  operator has been defined as a saturating operation.][71269] This was
  previously undefined behaviour, you can use the `{f64, f32}::to_int_unchecked`
  methods to continue using the current behaviour which may desirable in rare
  performance sensitive situations.

Internal Only
-------------
These changes provide no direct user facing benefits, but represent significant
improvements to the internals and overall performance of rustc and
related tools.

- [dep_graph Avoid allocating a set on when the number reads are small.][69778]
- [Replace big JS dict with JSON parsing.][71250]

netbsd-srcmastr pushed a commit to NetBSD/pkgsrc that referenced this pull request Jul 6, 2020
Pkgsrc changes:
 * Remove the clutter caused by the cross-compile setup from Makefile
   (Now consigned to my own private cross.mk file.)
 * Remove a couple of patches which are now integrated upstream.
 * Minor adjustments to a couple of other patches.
 * Adjust cargo checksums after upstream upgrades.
 * Belatedly bump the curl dependency
 * If doing a "dist" build, unset DESTDIR during the build phase,
   to work around a mysterious build bug deep in the bowels of llvm,
   causing llvm tools to be installed to a directory unexpecetd by
   the rest of the rust build, ref.
   rust-lang/rust#73132
   A "dist" build is not expected to be followed by an "install".
 * Bump nearly all bootstraps to 1.43.1; NetBSD earmv7hf bootstrap
   bumped to 1.44.0, as that one now finally builds and works.
