Also
* Make C++ offset_extractor binaries emit entire if/def condition
(including product vs non-product)
=> This makes it much nicer to look up offsets, as the preceding
#if condition will be the whole condition.
* Run the builds & offset extractions in parallel
This will make it easier to extend the cross product of our
configurations that require different offsets (e.g. sanitizers)
TEST=Manually run.
