In other words, if we need to pass a cc1 option to a specific sub-compilation, we'll need an arch-specific `-Xclang` variant. Does `-Xarch_foo -Xclang -Xarch_foo <foo-specific cc1 option>` work with this patch? Considering that sub-compilations *are* cc1 invocations, passing cc1 options is something that would be very useful as not all cc1 options can be directly controlled from the driver level, but most driver options not directly related to the pipeline construction can be overridden by cc1 options.
