It's been gone since #23945, before Rust 1.0. The former wrapping
semantics have also been available as inherent methods for a long time
now. There's no reason to keep this unused macro around.

allow const generics in const fn
This was explicitly forbidden before. As we were unable to think of a reason
why this should still be the case, this check has been removed.

Suggest .into() over try_into() when it would work
It would be better to suggest x.into() instead, which is shorter, cannot fail, and doesn't require importing a trait.
Tests have been added and made up to date.

ci: run mir-opt tests on PR CI also as 32-bit (for `EMIT_MIR_FOR_EACH_BIT_WIDTH`).
Background: #69916 and [`src/test/mir-opt/README.md`](https://github.com/rust-lang/rust/blob/master/src/test/mir-opt/README.md):
> By default 32 bit and 64 bit targets use the same dump files, which can be problematic in the
presence of pointers in constants or other bit width dependent things. In that case you can add
>
> ```
> // EMIT_MIR_FOR_EACH_BIT_WIDTH
> ```
>
> to your test, causing separate files to be generated for 32bit and 64bit systems.
However, if you change the output of such a test (intentionally or not), or if you add a test and it varies between 32-bit and 64-bit platforms, you have to run this command (for a x64 linux host):
`./x.py test --stage 1 --target x86_64-unknown-linux-gnu --target i686-unknown-linux-gnu --bless src/test/mir-opt`
Otherwise, bors trying to merge the PR will fail, since we test 32-bit targets there.
But we don't on PR CI, which means there's no way the PR author would know (unless they were burnt by this already and know what to look for).
This PR resolves that by running `mir-opt` tests for ~~`i686-unknown-linux-gnu`~~, on PR CI.
**EDIT**: switched to `armv5te-unknown-linux-gnueabi` to work around LLVM 7 crashes (see https://github.com/rust-lang/compiler-builtins/pull/311#issuecomment-612270089), found during testing.

The old naming is from ancient times when there was no MSVC support.
Also `uefi_base` -> `uefi_msvc_base`.
It will inherit from `msvc_base` in a future commit, plus a GNU UEFI target is also potentially possible.
* Rename Weak::as_raw to Weak::as_ptr for consistency with some other
types.
* The as_ptr for a dangling Weak pointer might return whatever garbage
(and takes that advantage to avoid a conditional).
* Don't guarantee to be able to do `Weak::from_raw(weak.as_ptr())` (even
though it'll still work fine).
Calls to `assemble_extension_candidates_for_traits_in_scope` with
`DUMMY_HIR_ID` as `expr_hir_id` are useless because the first thing
that this function does is to return `Ok(())` in this case.
Make LLVM version suffix independent of rustc version on dev channel
Remove rustc version from LLVM version suffix on dev channel,
avoiding the need for full rebuilds when switching between
branches with different LLVM submodule & rustc version.
Note: To avoid full rebuild, on subsequent LLVM submodule update, copy the
current value of `LLVM_VERSION_SUFFIX` from `build/*/llvm/build/CMakeCache.txt`,
to `version-suffix` in `config.toml`.
