[PATCH] D78762: build: use `find_package(Python3)` if available

[Nico Weber via Phabricator via cfe-commits]

thakis added a comment.

Is there more background on this somewhere? What's the advantage of using Python3_EXECUTABLE instead of just PYTHON_EXECUTABLE? Having Python3_EXECUTABLE be python 2 seems pretty surprising to me.

Also, this doesn't update some PYTHON_EXECUTABLEs, e.g. the one in lld/test. Is that intentional?
