For performance reasons the reproducers don't copy the files captured by the file collector eagerly, but wait until the reproducer needs to be generated. This is a problematic when LLDB crashes and we have to do all this signal-unsafe work in the signal handler. This patch uses a similar trick to clang, which has the driver invoke a new cc1 instance to do all this work out-of-process. This patch moves the writing of the mapping file as well as copying over the reproducers into a separate process spawned when lldb crashes. Differential revision: https://reviews.llvm.org/D89600
