Summary Retry process launch

rdar://173715411 is an intermittent bug in process launch which occurs only for very large binaries. If WebKit is built with code coverage instrumentation enabled, that pushes us over the troublesome threshold, and WebKit sometimes fails to launch its child processes. Provide a build-time option to add a retry loop for such launches, which enables us to run test suites even if coverage is enabled. Unless the make command line contains GCC_PREPROCESSOR_ADDITIONS=ENABLE_RETRY_LAUNCHES, or that option is specified in some other way, this code change has no effect.
