When running the tests with a toolchain built with the "early swift
driver", we would incorrectly process the command line, losing the empty
string argument to `-sdk` which would then incorrectly process the
remainder of the command line. This allows most of the remaining tests
to pass with the early swift driver on Windows (assuming that the paths
are adjusted properly).
Localize the hack to infer simulator-ness of the target in the driver
itself, when it first processes the target. Emit a warning about the
missing "-simulator" and correct the triple immediately.
This gives a longer grace period for tools that might still not pass
through the simulator environment, while narrowing the hack.
