9e58b2c401 [Backtracing] Make this macOS only for now.
The Linux Swift compiler is ICEing when building _Backtracing, while
Windows still needs some tweaks.  In order to land this sooner, disable
this code except for macOS.

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.
