Jordan Rose 47872d9190 [Driver] Transfer all ownership of Actions to the Compilation. ...

Previously, Actions were responsible for freeing their inputs...
except for the ones that weren't. Or the ones that were supposed
to, but then they needed to share an input, so they couldn't anymore.
If this sounds ridiculous, you're right; now Actions are just
immediately allocated and owned by the Compilation.

The graph structure of the actions is still useful for some things; in
particular, "top-level" actions get to put their outputs somewhere
permanent rather than TMPDIR. But I expect these things to get cleaned
up in the future too.
