This change makes error and warning annotations mandatory in UI tests.
The only exception are tests that use error patterns to match compiler
output and don't have any annotations.
Previously, when compilation succeeded, neither error patterns nor error
annotation would be validated. Additionally, when compilation failed,
only error patterns would be validated if both error patterns and error
annotation were present.
Now both error patterns and error annotation are validated when present,
regardless of compilation status. Furthermore, for test that should run,
the error patterns are matched against executable output, which is what
some of tests already expect to happen, and when #65506 is merged even
more ui tests will.
Make `promote_consts` emit the errors when required promotion fails
A very minimal version of #65942.
This will cause a generic "argument X is required to be a constant" message for `simd_shuffle` LLVM intrinsics instead of the [custom one](caa1f8d7b3/src/librustc_mir/transform/qualify_consts.rs (L1616)). It may be possible to remove this special-casing altogether after rust-lang/stdarch#825.

Dual proc macro hash
This PR changes current `-Z dual-proc-macro` mechanism from resolving only by name to including the hash of the host crate inside the transistive dependency information to prevent name conflicts.

submodules: Bump RLS to 58869107ec162a821a4bee53cdd3f51c84cda3ea
Most importantly it contains d267b49c2f which fixes the RLS build whenever Clippy is built successfully in Rust CI.

Use rustc-workspace-hack for rustbook
As rustbook now depends transitively on openssl, it needs access to the
rustc-workspace-hack/all-static feature to pick up openssl-sys/vendored.
This fixes the rust build with `all-static = true` on systems where
openssl is not installed (e.g. when cross-compiling).
Re-enable Emscripten's exception handling support
Passes LLVM codegen and Emscripten link-time flags for exception
handling if and only if the panic strategy is `unwind`. Sets the
default panic strategy for Emscripten targets to `unwind`. Re-enables
tests that depend on unwinding support for Emscripten, including
`should_panic` tests.

Fixes ##65888
Redesign the interface to the unikernel HermitCore
We are developing the unikernel HermitCore, where the kernel is written in Rust and is already part of the Rust Standard Library. The interface between the standard library and the kernel based on a small C library. With this pull request, we remove completely the dependency to C and use lld as linker. Currently, the kernel will be linked to the application as static library, which is published at https://github.com/hermitcore/libhermit-rs.
We don’t longer support the C interface to the kernel. Consequently, we remove this part from the Rust Standard Library.

Split the rustc target libraries into separate rustc-dev component
This is re-applies a squashed version of #64823 as well as including #65337 to fix bugs noted after merging the first PR.
The second PR is confirmed as fixing windows-gnu, and presumably also fixes other platforms, such as musl (i.e. #65335 should be fixed); `RUSTUP_DIST_SERVER=https://dev-static.rust-lang.org rustup toolchain install nightly-2019-10-16` can be installed to confirm that this is indeed the case.
Remove `InternedString`
This PR removes `InternedString` by converting all occurrences to `Symbol`. There are a handful of places that need to use the symbol chars instead of the symbol index, e.g. for stable sorting; local conversions `LocalInternedString` is used in those places.

With #65251 landed there's no need to build two LLVM backends and ship
them with rustc, every target we have now uses the same LLVM backend!
This removes the `src/llvm-emscripten` submodule and additionally
removes all support from rustbuild for building the emscripten LLVM
backend. Multiple codegen backend support is left in place for now, and
this is intended to be an easy 10-15 minute win on CI times by avoiding
having to build LLVM twice.
Check all files in `src/test` for `borrowck_graphviz_postflow`
This attribute causes DOT files to be generated in the top-level directory. It is intended to be used only temporarily and should never appear on master. This also tells git to ignore DOT files in the root or the `mir_dump` directory, which `-Z dump-mir` uses by default.
This will prevent #65071 from occurring again. It needs to be merged after #65629, otherwise `tidy` will start failing.
