SwiftPM and `swift test` use Swift Argument Parser which allows developers to specify arguments of the form `--foo=bar`. Our bare-bones argument parser doesn't currently recognize that pattern, which means that the developer could write `--foo=bar` but get the wrong behavior. This PR adds support for that pattern by changing how we parse command-line arguments to allow for both `--foo bar` and `--foo=bar`.
