Type annotations are shared between the MIR of a function and the
promoted constants for that function, so keep them in the type checker
when we check the promoted MIR.
Remove NodeId from more HIR nodes
The next iteration of HirIdification (#57578).
Removes `NodeId` from:
- [x] `Stmt`
- [x] `Local`
- [x] `Field`
- [x] `AnonConst`
- [x] `TraitItem`
- [x] `ImplItem`
- [x] `TypeBinding`
- [x] `Arg`
- [x] `TraitRef`
- [x] `VisibilityKind`
It will most probably break clippy again; I'd appreciate a **delegate** again if/when it is good to go so I can attach a clippy fix later.

Put Local, Static and Promoted as one Base variant of Place
Related to #52708
The `Place` 2.0 representation use a `Base` variant for `Local`, `Static` and `Promoted` so we start making this change in the current `Place` to make the following steps simpler.

rustc: Update LLVM, remove dead wasm code
This commit updates the LLVM branch to the rebased version of the
upstream release/8.x branch. This includes a wasm patch which means that
the `rewrite_imports` pass in rustc is no longer needed (yay!) and we
can instead rely on `wasm-import-module`, an attribute we're already
emitting, to take care of all the work.
Support defining C compatible variadic functions
## Summary
Add support for defining C compatible variadic functions in unsafe rust with
`extern "C"` according to [RFC 2137].
## Details
### Parsing
When parsing a user defined function that is `unsafe` and `extern "C"` allow
variadic signatures and inject a "spoofed" `VaList` in the new functions
signature. This allows the user to interact with the variadic arguments via a
`VaList` instead of manually using `va_start` and `va_end` (See [RFC 2137] for
details).
### Codegen
When running codegen for a variadic function, remove the "spoofed" `VaList`
from the function signature and inject `va_start` when the arg local
references are created for the function and `va_end` on return.
## TODO
- [x] Get feedback on injecting `va_start/va_end` in MIR vs codegen
- [x] Properly inject `va_end` - It seems like it should be possible to inject
`va_end` on the `TerminatorKind::Return`. I just need to figure out how
to get the `LocalRef` here.
- [x] Properly call Rust defined C variadic functions in Rust - The spoofed
`VaList` causes problems here.

[RFC 2137]: https://github.com/rust-lang/rfcs/blob/master/text/2137-variadic.md
We'll use this as a temporary measure to get an LLVM update landed, but
we'll have to go through and update images later to make sure they've
got the right toolchains.
Function signatures with the `variadic` member set are actually
C-variadic functions. Make this a little more explicit by renaming the
`variadic` boolean value, `c_variadic`.
- Move closures defined in codegen_terminator into a separate helper
structure and implementation.
- Create helper functions for each of the complex match arms on the
terminators kind in codegen_terminator.
Normalize the type Self resolves to in an impl
This is required at the very least in order to evaluate associated
constants for arrays.

update scoped_tls to 1.0
scoped_tls has been updated to version 1.0
This PR will hopefully merge flawlessly :)
This fixes, among others, https://github.com/alexcrichton/scoped-tls/issues/9
Note, that the nightly feature has been removed in 64bd7b84a1
std: docs: Disable running several Stdio doctests
* A number of `Stdio` related doc examples include running the "rev"
command to illustrate piping commands. The majority of these tests are
marked as `no_run` except for two tests which were not
* Not running these tests is unlikely to cause any negative impact, and
doing so also allows the test suite to pass in environments where the
"rev" command is unavailable
