This applies the HIR changes from the previous commits to the AST, and
is thus a syntax-[breaking-change]
Renames `PatKind::Vec` to `PatKind::Slice`, since these are called slice
patterns, not vec patterns. Renames `TyKind::Vec`, which represents the
type `[T]`, to `TyKind::Slice`. Renames `TyKind::FixedLengthVec` to
`TyKind::Array`.
update mips64* data-layout
I tried to compile some (`#![no_core]`) code for the `mips64` targets on the latest nightly and got ICE's about mismatched data layouts. I updated the data layouts to match the listed llvm defaults.

Funnily enough, this seems to be the exact reverse of what @japaric did in 2222d437a7 as part of #36024.
Remove requirement to use 10.7 (fixes macOS)
Fixes https://github.com/rust-lang/rust/issues/36650 by removing the requirement to use 10.7. @alexcrichton pointed out that the buildbots won't be affected, since they set the requirement with an environment variable.
This should now allow rustbuild to build Rust on macOS (nee OS X)

rustc: Tweak expansion order of custom derive
This commit alters the expansion order of custom macros-1.1 style `#[derive]`
modes. Instead of left-to-right the expansion now happens in three categories,
each of which is internally left-to-right:
* Old-style custom derive (`#[derive_Foo]`) is expanded
* New-style custom derive (macros 1.1) is expanded
* Built in derive modes are expanded
This gives built in derive modes maximal knowledge about the struct that's being
expanded and also avoids pesky issues like exposing `#[structural_match]` or
`#[rustc_copy_clone_marker]`.

libtest: add a --skip flag to the test runner
This flag takes a FILTER argument and instructs the test runner to skip
the tests whose names contain the word FILTER. --skip can be used
several times.
---
My motivation for submitting this is that while using [smoke] to run `std` unit tests for cross
targets I found that a few of the tests always fail due to limitations in QEMU (it can't handle too
many threads) and I'd like to skip these problematic tests from the command line to be able to run
the rest of the unit tests.
[smoke]: https://github.com/japaric/smoke
I know there is another mechanism to skip tests: `#[ignore]` but this doesn't work in my use case
because I can't (easily) modify the source of the standard libraries to `#[ignore]` some tests. And
even if I could, the change would involve conditionally ignoring some tests for some targets but
that's not a perfect solution because those tests should pass if executed on real hardware so they
should not be `#[ignored]` in that scenario.

rustc: Use a special filename for macros 1.1
This "special filename" is surrounded by `<>` to ensure that
`FileMap::is_real_file` returns `false`. This way the "files" parsed here aren't
emitted as dep info `.d` files and don't confuse Cargo about non-existent files.
Closes#36625
Now a target can define its panic strategy in its specification. If a
user doesn't specify a panic strategy via the command line, i.e. '-C
panic', then the compiler will use the panic strategy defined by the
target specification.
Custom targets can pick their panic strategy via the "panic-strategy"
field of their target specification JSON file. If omitted in the
specification, the strategy defaults to "unwind".
