All refutable patterns and function parameters marked with 'var'
is now an error.
- Using explicit 'let' keyword on function parameters causes a warning.
- Don't suggest making function parameters mutable
- Remove uses in the standard library
- Update tests
rdar://problem/23378003
- Remove free Swift functions for advance and distance and replace
them with protocol extension methods:
- advancedBy(n)
- advancedBy(n, limit:)
- distanceTo(end)
- Modernize the Index tests
- Use StdlibUnittest
- Test for custom implementation dispatch
Perf impact: No significant changes reported in the
Swift Performance Measurement Tool.

Swift SVN r30958
The type checker hits a recursion when checking the conformance to
CollectionType in UnsafeMutableBufferPointer, which requires
_withUnsafeMutableBufferPointerIfSupported, which mentions
UnsafeMutableBufferPointer. The easiest fix for now is to break the
recursion in the library.
Reverting this change is tracked by: <rdar://problem/21933004> Restore
the signature of _withUnsafeMutableBufferPointerIfSupported() that
mentions UnsafeMutableBufferPointer

This covers:
- Lifetime-extending wrappers, like withExtendedLifetime, withCString, and withUnsafe*Pointer
- 'map' and friends on Optional
- 'indexOf'
A few APIs I haven't gotten to yet in this first pass:
- Autoclosure APIs, like assert, &&, etc.
- the 'isOrderedBefore' predicate for sorting APIs. The sorting implementation does some microoptimizations with 'inout' closures that violate rethrows checking.
- Strict 'map', 'filter', and friends on CollectionType. These need some plumbing in Lazy to be able to thread a Result-forming transformation through.
This version of the patch updates some protocol customization implementations that I missed the first time around, and includes the tests I forgot to add in the previous iteration.
