Auto merge of #115306 - tmiasko:encode-reachable-mir, r=cjgillot

Encode only MIR reachable from other crates

Only reachable items might participate in the code generation in the
downstream crates. Omit redundant optimized MIR of unreachable items
from a crate metadata.

Additionally, include reachable closures in reachable set, so that
unreachable closures can be omitted on the same basis.
