Include bounds from promoted constants in NLL
Previously a promoted function wouldn't have its bound propagated out to
the main function body.
When we visit a promoted, we now type check the MIR of the promoted
and transfer any lifetime constraints to back to the main function's MIR.
Fixes#57170

Before this commit, if you're running x.py directly on a system where
`python` is symlinked to Python 3, then the `python` config option will
default to a Python 3 interpreter. This causes debuginfo tests to fail
with an opaque error message, since they have a hard requirement on
Python 2.
This commit modifies the Python probe behavior to look for python2.7 and
python2 *before* using the interpreter used to execute `x.py`.
Originally added in #55935 to test build times, this was reverted
in #56201 due to a belief that it caused the exit code 259 spurious
errors. We've since learned, however, that the 259 exit code is likely
not related to this image update as we're getting it in a number of
locations now.
VS2017 looks like it may be required to compile LLVm in the near future,
notably discovered by #58408 where we attempted to update LLVM.
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.
