Fix get_first false negative for VecDeque
fixes#11695
Also run the lint on `VecDeque` and suggest using `.front()` instead of `.get(0)` when trying to access the first element.
PS: At first I implemented the VecDeque Lint in a separate `if_chain` (see the previous commit).
Let me know if thats the preferred way, then I will remove the refactoring into one block.
changelog: [`get_first`]: fix false negative: Also lint `VecDeque` and suggest using `front()`
Most notably, this commit changes the `pub use crate::*;` in that file
to `use crate::*;`. This requires a lot of `use` items in other crates
to be adjusted, because everything defined within `rustc_span::*` was
also available via `rustc_span::source_map::*`, which is bizarre.
The commit also removes `SourceMap::span_to_relative_line_string`, which
is unused.
Fix switch_stdout_to on Windows7
The `switch_stdout_to` test was broken on Windows7, as deleting the temporary test folder would fail since the `switch-stdout-output` file we redirected the stdout to is never closed, and it's impossible on Win7 to delete an opened file.
To fix this issue, we make `switch_stdout_to` return the previous handle. Using this, we add a new `switch_stdout_to` call at the end of the test to return the stdio handles to their original state, and recover the handle to the file we opened. This handle is automatically closed at the end of the function, which should allow the temporary test folder to be deleted properly.
The comment just below the first one describes how the `impl !Send for
FatalError` makes it impossible to `panic!(FatalError)`.
And the second one should be `panic_any` instead of `panic!`.

Do not assert in op_to_const.
`op_to_const` is used in `try_destructure_mir_constant_for_diagnostics`, which may encounter invalid constants created by optimizations and debugging.

Avoid the path trimming ICE lint in error reporting
Types or really anything in MIR should never be formatted without path trimming disabled, because its formatting often tries to construct trimmed paths. In this case, the lint turns a nice error report into an irrelevant ICE.
Add FileCheck annotations to MIR-opt inlining tests
Part of #116971, adds FileCheck annotations to MIR-opt tests in `tests/mir-opt/inline`.
I left out a few (such as `inline_cycle`) where it mentioned that the particular outcome of inlining isn't important, just that the inliner doesn't get stuck in an infinite loop.

Account for `ref` and `mut` in the wrong place for pattern ident renaming
If the user writes `S { ref field: name }` instead of `S { field: ref name }`, we suggest the correct code.

Set max_atomic_width for riscv32*-esp-espidf to 32
Fixes#117305
> Since riscv32 does not have 64-bit atomic instructions, I do not believe there is any way to fix this problem other than setting max_atomic_width of these targets to 32.
This is a breaking change because Atomic\*64 will become unavailable, but all affected targets are tier 3, and the current Atomic*64 violates the standard library's API contract and can cause problems with code that rely on the standard library's atomic types being lock-free.
