This is a resubmit of r223548, which was reverted due to breaking tests on Linux and Mac. This resubmit fixes the reason for the revert by adding back some accidentally removed code which appends -c to the command line when running /bin/sh. This resubmit also differs from the original patch in that it sets the architecture on the ProcessLaunchInfo. A follow-up patch will refactor this to separate the logic for different platforms.
