JDevlieghere requested review of this revision.

Use the newly added spawnattr API, `posix_spawnattr_setarchpref_np`, to select a slice preferences per cpu and subcpu types, instead of just cpu with `posix_spawnattr_setarchpref_np`. In the patch it only does this for `x86_64` and `x86_64h`, but I would like to extend the parsing to more subtypes.

Tested by compiling a fat binary with different print statements depending on the architecture. I considered adding a test for it, but it doesn't seem worth the hassle to figure out the host architecture and the availability.
