- Fix error in `last(where:)` example
- Improve MemoryLayout, UnsafePointer, and integer operator discussions
- Clean up ranges and random APIs
- Revisions to overflow operators and the SignedNumeric requirements
- Standardize on 'nonoptional' in remaining uses
* [stdlib] Update complexity docs for seq/collection algorithms
This corrects and standardizes the complexity documentation for Sequence
and Collection methods. The use of constants is more consistent, with `n`
equal to the length of the target collection, `m` equal to the length of
a collection passed in as a parameter, and `k` equal to any other passed
or calculated constant.
* Apply notes from @brentdax about complexity nomenclature
* Change `n` to `distance` in `index(_:offsetBy:)`
* Use equivalency language more places; sync across array types
* Use k instead of n for parameter names
* Slight changes to index(_:offsetBy:) discussion.
* Update tests with new parameter names
* Use the `__has_include` and `GRND_RANDOM` macros
* Use `getentropy` instead of `getrandom`
* Use `std::min` from the <algorithm> header
* Move `#if` out of the `_stdlib_random` function
* Use `getrandom` with "/dev/urandom" fallback
* Use `#pragma comment` to import "Bcrypt.lib"
* <https://docs.microsoft.com/en-us/cpp/preprocessor/comment-c-cpp>
* <https://clang.llvm.org/docs/UsersManual.html#microsoft-extensions>
* Use "/dev/urandom" instead of `SecRandomCopyBytes`
* Use `swift::StaticMutex` for shared "/dev/urandom"
* Add `getrandom_available`; use `O_CLOEXEC` flag

Revert to checking if T is > UInt64
This implements the new last(where:), and lastIndex(of/where:) methods as
extensions on `BidirectionalCollection`, which partially implements SE-204.
The protocol requirements for `Sequence` and `Collection` as described
in the proposal need to wait until there's a solution for picking up the
specialized versions in types that conditionally conform to `BidirectionalCollection`.
* [stdlib] Remove MutableCollection.sorted methods
This removes the implementations of sorted() and sorted(by:) on Mutable-
Collection, which only changed some minor wording in the docs.
This also adds documentation to the partition(by:) implementations so that
they will appear downstream.
* [stdlib] De-gyb CollectionAlgorithms.swift
* Update tests for MutableCollection.sorted() changes
