0a8058ca6a [Integer protocols] Make BinaryInteger.Words conform to RandomAccessCollection. 
Require that BinaryInteger.Words conform to RandomAccessCollection with
an Index type of Int, simplifying clients.

Fixes rdar://problem/36410936.

190c7d6b9f Default implementation of isMultiple(of:) on BinaryInteger 
In order to provide source compatibility with existing user types conforming to BinaryInteger, we want to have a default implementation available. It's somewhat difficult to provide a good default implementation that correctly handles arbitrary non-symmetrical ranges in the face of negative divisors, so fall back on testing divisibility of the magnitudes, which avoids the problem.

On the plus side, this default implementation works fine for types conforming to UnsignedInteger, which lets us move the FixedWidthInteger implementation down to FixedWidthInteger & SignedInteger, and simplify it in the process.

c1f25e0673 [SE-0225] Implementation of isMultiple for BinaryInteger. (#18689) 
* Implement SE-0225 (BinaryInteger.isMultiple(of:))

A default implementation is provided for FixedWidthInteger, with very basic test coverage included.

35db40c9f9 Make BinaryInteger._binaryLogarithm() return Int instead of Self (#18219) 
Returning `Self` was probably a hack from when shifts were required to be homogenous and we didn't have good generic inits between integer types. Returning Int is more natural, because:

1. Dimensional analysis says that we shouldn't expect the logarithm to have the same type.
2. Int is guaranteed to be able to represent any object size, and BinaryInteger does not admit sparse representations, so the logarithm of the value cannot exceed allocated storage size.
3. Every single use case in the stdlib and tests is either unchanged or simplified by this change.

b67d5f0cf7 test: convert rm -rf && mkdir -p into %empty-directory 
This converts the instances of the pattern for which we have a proper
substitution in lit.  This will make it easier to replace it
appropriately with Windows equivalents.

This reverts commit 3f0d1e61aa.

The copy constructors don't really solve any problems, but produce extra
work for the overload resolution.
