The SPI that XCTest exposes to the overlay has Objective-C semantics,
while anything exposed to Swift code via @asmname needs Swift semantics.
Add a bridge to the overlay that handles this adaptation.
Addresses <rdar://problem/17408423>.
Swift SVN r20932
Rather than use a header file and -import-objc-header, use @asmname and
@objc_block to tell the overlay about the Objective-C function used to
capture exceptions.
Further addresses <rdar://problem/16453199>.
Swift SVN r20929
Since Swift itself has no exception support, use an Objective-C helper function
to evaluate a block and return an NSDictionary indicating whether an exception
was thrown out of that block (and if so, which exception).

Swift SVN r20880
We need to actually keep the XCTest support in an overlay for now.
This reverts commit 4a2726862634a553483943baf39a251ac8071e37.
Addresses <rdar://problem/17423669>.
Swift SVN r19101
The XCTest support for Swift is now built as part of XCTest.framework
itself, so the overlay is no longer necessary.
Addresses <rdar://problem/17383462>.
Swift SVN r19016
XCTest needs a way to get the demangled name of a test case class,
so provide one by overriding NSObject.className.
