String itsef should only expose Unicode-correct algorithms, like proper
substring/prefix/suffix search, enumerating words/lines/paragraphs, case
folding etc. Promoting sequence-centric algorithms to methods on String
is not acceptable since it invites users to write wrong code. Thus,
String has to lose its SequenceType conformance.
Nevertheless, we recognize that sometimes it is useful to manipulate the
String contents on lower levels (UTF-8, UTF-16, Unicode scalars,
extended grapheme clusters), for example, when implementing high-level
Unicode operations, so we can't remove low-level operations
altogether. For this reason, String provides nested "views" for the
first three low-level representations, but grapheme clusters were in a
privileged position -- String itself is a collection of grapheme
clusters. We propose to add a characters view that will represent the
String as a collection of Character values.

Doing so is safe even though we have mock SDK. The include paths for
modules with the same name in the real and mock SDKs are different, and
the module files will be distinct (because they will have a different
hash).
This reduces test runtime on OS X by 30% and brings it under a minute on
a 16-core machine.
This also uncovered some problems with some tests -- even when run for
iOS configurations, some tests would still run with macosx triple. I
fixed the tests where I noticed this issue.

This decreases total testing time by over a minute on my old Mac Pro.
It probably has much less effect on systems with fewer cores, but shouldn't
be any worse there.
