Fix promotion stability hole in old borrowck #53699

oli-obk · 2018-08-25T13:35:40Z

I screwed up the promotion stability checks. Big time. They were basically nonexistant. We had tests for it. I also screwed up said tests. This is in stable already :(

Basically stability checks of promotion only worked if you tried to use a const fn defined in the same crate.

The one regression does not show any errors except for "compilation failed"... I presume spurious (passes locally)
