The lit and testsuite changes are hacks to work around the problems with the -enable-source-import model. Some day, we’ll get a “real” mock SDK with compiled overlays so these hacks can go away.
Swift SVN r26327
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).
Swift SVN r25185
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.
Swift SVN r24504
When we import factory methods as initializers, we can end up with two initializers that have the same name and type but different kinds. This will differentiate them. Tripped over this while investigating <rdar://problem/17411843>
