Alex Crichton 8ef3f69ffb Add a disabled builder for aarch64 emulated tests 
This commit adds a disabled builder which will run all tests for the standard
library for aarch64 in a QEMU instance. Once we get enough capacity to run this
on Travis this can be used to boost our platform coverage of AArch64

rustdoc: fix layout of Fields section in documentation for unions

Previously, the union fields would all render on the same line with
hideous spacing; comparison to the analogous section for structs makes
it undoubtable that `display: block` is the true intent.

Concisely and definitively resolves #43404 and its perfidious
malignancy.

bors 8d22af87d8 Auto merge of #43059 - Mark-Simulacrum:rustbuild-2.0, r=alexcrichton 
Rework Rustbuild to an eagerly compiling approach

This introduces a new dependency on `serde`; I don't believe that's a problem since bootstrap is compiled with nightly/beta always so proc macros are available. Compile times are slightly longer -- about 2-3x (30 seconds vs. 10 seconds). I don't think this is too big a problem, especially since recompiling bootstrap is somewhat rare. I think we can remove the dependency on Serde if necessary, though, so let me know.

std: Cut down #[inline] annotations where not necessary

This PR cuts down on a large number of `#[inline(always)]` and `#[inline]`
annotations in libcore for various core functions. The `#[inline(always)]`
annotation is almost never needed and is detrimental to debug build times as it
forces LLVM to perform inlining when it otherwise wouldn't need to in debug
builds. Additionally `#[inline]` is an unnecessary annoation on almost all
generic functions because the function will already be monomorphized into other
codegen units and otherwise rarely needs the extra "help" from us to tell LLVM
to inline something.

Overall this PR cut the compile time of a [microbenchmark][1] by 30% from 1s to
0.7s.

It's not the prettiest, but whenever #41850 gets resolved, this should be able to be improved.

bors 68be86d032 Auto merge of #42973 - zackmdavis:json_byte_position_to_start_at_top_of_file, r=nrc 
make JSON error byte position start at top of file

The `hi` and `lo` offsets in a span are relative to a `CodeMap`, but this
doesn't seem to be terribly useful for tool consumers who don't have the
codemap, but might want the byte offset within an actual file?

I couldn't get @killercup's [example](https://github.com/rust-lang/rust/issues/35164#issuecomment-301436519) to run, perhaps due to the limitations of the merely-stage-1 compiler that I built (error was `libproc_macro-456500c7095d8fbe.so: cannot open shared object file: No such file or directory`)??—but a dummy project confirms that the byte offsets have successfully been changed to be file-relative—
