  FunctionAttrs: Basic propagation of nofpclass

Perform caller->callee propagation of nofpclass on callsites. As
far as I can tell the only prior callsite to callee propagation here
was for norecurse. This doesn't handle transitive callers.

I was hoping to avoid doing this, and instead get attributor/attributor-light
enabled in the default pass pipeline. nofpclass propagation enabled by
default is the main blocker for eliminating the finite_only_opt global
check in device-libs, but this single level of propagation is most likely
sufficient for that use. Implemnting this here is probably the most expedient
path to removing the control library.
