Print a backtrace when query forcing fails.

The aim of this PR is to help debugging incremental compilation bugs where query forcing panics.
For instance: rust-lang#90682 rust-lang#90697 rust-lang#90715 rust-lang#90739 rust-lang#91401

These bugs happen when the dep-graph attempts to force a dep-node whose fingerprint does not correspond to an actual DefPathHash. PR rust-lang#91741 attempts to hide this bug.

I still don't know how to reproduce these bugs, so I sadly could not test this debugging device.
