Update doc comments that refer to config parameter
This commit updates the `source_file_to_parser` and the
`maybe_source_file_to_parse` function's doc comments which currently
refer to a `config` parameter. The doc comments have been updated to
refer to the `session` parameter similar to the doc comment for
`try_file_to_source_file`, which also takes a `&Session` parameter.
remove some provenance-related machine hooks that Miri no longer needs
Then we can make `scalar_to_ptr` a method on `Scalar`. :)

The implementation of BufReader contains a lot of redundant checks.
While any one of these checks is not particularly expensive to execute,
especially when taken together they dramatically inhibit LLVM's ability
to make subsequent optimizations.
Test codegen of atomic compare-exchange with additional memory orderings
* Add a test for atomic operations introduced in #97423 & #98383.
* Add a test for fallback code generation strategy used on LLVM 12 introduced in #98385. Use a separate test case instead of a revision system since test will be gone once LLVM 12 is no longer supported.

Fix missing fields check on destructuring assignment
Fixes#12838
When checking if the record literal in question is an assignee expression or not, the new fn `is_assignee_record_literal` iterates over its ancestors until it is sure. This isn't super efficient, as we don't cache anything and does the iteration for every record literal during missing fields check. Alternatively, we may want to have a field like `assignee` on `hir_def::Expr::{RecordLit, Array, Tuple, Call}` to tell if it's an assignee expression, which would be O(1) when checking later but have some memory overhead for the field.
Revert "Mark atomics as unsupported on thumbv6m"
This is a breaking change for the `thumbv6m` target. See #99668 for discussion on how we can proceed forward from here.
This reverts commit 7514610219.

fix: don't replace default members' body
cc #12779, #12821
addresses https://github.com/rust-lang/rust-analyzer/pull/12821#issuecomment-1190157506
`gen_trait_fn_body()` only attempts to implement required trait member functions, so we shouldn't call it for `Implement default members` assist.
This patch also documents the precondition of `gen_trait_fn_body()` and inserts `debug_assert!`, but I'm not entirely sure if the assertions are appropriate.
