Alastair Houghton 65a6aae04e [Backtracing] Add swift-backtrace to the build.
This is Swift's external backtracer.  It's written in Swift, and it's
responsible for generating nice backtraces when Swift programs crash.
It makes use of the new `_Backtracing` library, which is also (mostly,
aside from some assembly language) implemented in Swift.

What is this?
=============
The libexec directory contains the source code for auxiliary executables that
ship with the Swift runtime, as opposed to being part of the toolchain.
On UNIX-like platforms, if the runtime is installed in /usr/lib/swift (for
instance), these are things that you would expect to find in /usr/libexec/swift.
