Grab whatever ProgramStart has stored in executionEnvironment.argc and subtract 1 (based on the assumption that ProgramStart is called with a C-style argc that counts the command name as an argument). Spoiler alert: The tests will evolve into fixtures when we implement GET_COMMAND_ARGUMENT etc. Differential Revision: https://reviews.llvm.org/D109048
