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.

Refuse to load a module if it was compiled for a different architecture or
OS, or if its minimum deployment target is newer than the current target.
Additionally, provide the target triple as part of pre-loading validation
for clients who care (like LLDB).

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 currently only works with Clang modules, since there's no way to specify
requirements for a Swift module.
Also, update some tests with a fake Foundation module to make sure they pick
up the fake Foundation adapter instead of the real one.
