<pre>After this patch: <a href="https://reviews.llvm.org/D69825">https://reviews.llvm.org/D69825</a>
multiple TUs cause really high memory usage. This is because each invocation of
the CC1Command isn't cleaning up after itself thanks to -disable-free. I
believe that in cases where there will be more than 1 CC1 invocation we need to
disable the driver's addition of the disable-free flag for all but the last CC1
invocation.</pre>
