Make it possible to capture reproducers from the API test suite. Given the symmetry between capture and replay, this patch also adds the necessary code for replay. For now this is a NO-OP until the corresponding reproducer instrumentation changes land. For more info please refer to the RFC on lldb-dev: http://lists.llvm.org/pipermail/lldb-dev/2020-April/016100.html Differential revision: https://reviews.llvm.org/D77588
