Issue Description:
SwiftPM should have a feature to automatically minimize a package to the smallest package to pass some test predicate (supplied by a shell script, for example).
This is invaluable tool for getting high quality / actionable bug reports for compiler crashes, build failures, etc. from developers who may not otherwise be able to share their source code.
Similar tools in this space are:
C-Reduce: https://embed.cs.utah.edu/creduce/
Delta: http://delta.tigris.org
Bugpoint: http://llvm.org/docs/Bugpoint.html
and we know from experience that these tools can be very powerful at efficiently reducing even very large test inputs to small test cases.
