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 `src/llvm-emscripten` submodule
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.

Disable Go and OCaml bindings when building LLVM
Instead of instaling OCaml bindings in a location where installation
will not fail, don't build them in the first place.

- Compatible with Emscripten 1.38.46-upstream or later upstream.
- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the old incorrect wasm32 C call ABI with the correct one,
preserving the old one as wasm32_bindgen_compat for wasm-bindgen
compatibility.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Uses EMCC_CFLAGS on CI to avoid the timeout problems with #63649.

This splits out a rustc-dev component with the compiler crates, and
keeps the status quo of default installed files on nightly. The default
changing to not install compiler libraries by default is left for a
future pull request.
However, on stable and beta, this does remove the compiler libraries
from the set of libraries installed by default, as they are never needed
there (per our stability story, they "cannot" be used).

minimize the rust-std component
This changes the `rust-std` dist component to only include the artifacts of compiling the `libstd` step, as listed in `.libstd.stamp`. This does include `test` and `proc-macro` as well. The remaining _unstable_ libraries that are built as part of `rustc` are packaged into a new `rustc-dev` component, intended for use in the development of closely related tools (clippy, miri, rls).
Here are the component sizes from the [try build](https://dev-static.rust-lang.org/dist/2019-10-07/index.html):
| Name | Size
| --- | ---
| rust-std-nightly-x86_64-unknown-linux-gnu.tar.gz | 23.94 MiB
| rust-std-nightly-x86_64-unknown-linux-gnu.tar.xz | 17.4 MiB
| rustc-dev-nightly-x86_64-unknown-linux-gnu.tar.gz | 182.03 MiB
| rustc-dev-nightly-x86_64-unknown-linux-gnu.tar.xz | 157.91 MiB

make it possible to add args to cargo in x.py
eg. make it easier to test -Ztimings for rustc

- the old interface between HermitCore and the Rust Standard Library
based on a small C library (newlib)
- remove this interface and call directly the unikernel
- remove the dependency to the HermitCore linker
- use rust-lld as linker

- Refactors the Emscripten target spec to share code with other wasm
targets.
- Replaces the incorrect wasm32 C call ABI with the old asmjs
version, which is correct for both wasm32 and JS.
- Updates the varargs ABI used by Emscripten and deletes the old one.
- Removes the obsolete wasm32-experimental-emscripten target.
- Temporarily makes Emscripten targets use panic=abort by default
because supporting unwinding will require an LLVM patch.

This is needed to ensure that the crates during a normal build are
shared with the crates during testing, otherwise they'll end up hasing
differently and we'll recompile crates like `core` during tests.

Turns out Cargo favors RUSTFLAGS!
|
|
|
|
|
|
This logic is *super* old and can be tweaked and moved into `builder.rs`
|
|
Instead let's do this via `RUSTFLAGS` in `builder.rs`. Currently
requires a submodule update of `stdarch` to fix a problem with previous
compilers.

No longer needs to live in `rustc.rs`

No longer any need for them to live in `rustc.rs`!
|
|
This commit changes the return type of `Builder::cargo` to return a
builder that allows dynamically adding more `RUSTFLAGS` values
after-the-fact. While not used yet, this will later be used to delete
more of `rustc.rs`

This commit ensure that we handle target-specific env vars for RUSTFLAGS
through Cargo as well.
