The Clang importer introduces a number of synthesized conformances for
imported enums (normal, NS_ENUMS, or NS_OPTIONS-based all have the
same issue) that aren't used in most translation units. Rather than go
through the effort of fully checking these conformances and generating
SIL for them always, rely on semantic analysis to force them to be
fully checked when the conformance is required. This cuts down on the
amount of work we need to do for imported enumeration types
considerably. For a simple program consisting of only:
import Foundation
var str = NSString()
My not-entirely-scientific measurements show that:
* Time to parse + type-check is reduced by 34%
* Time to generate SIL is reduced by 50%
* Time to generate IR is reduced by 47%
* SIL output size is reduced by 66%

This is required to correctly use the mock SDK when the SDK overlay is
built and tested separately. (Otherwise, the mock SDK might not get
used, because the overlay SDK options would expand from the
%-substitution, appear first on the command line, and shadow the mock
SDK in the search path).

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.

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.

Mechanically add "Type" to the end of any protocol names that don't end
in "Type," "ible," or "able." Also, drop "Type" from the end of any
associated type names, except for those of the *LiteralConvertible
protocols.
There are obvious improvements to make in some of these names, which can
be handled with separate commits.
Fixes <rdar://problem/17165920> Protocols `Integer` etc should get
uglier names.
