[filter_map_bool_then]: Don't ICE on late bound regions

[Centri3]

Fixes #11309

Also lints &NonCopy now, since any & is Copy. That was accidental, but it seems that this is a consequence (or improvement!) of this fix.

Oh this is because it no longer calls peel_refs, though I suppose this works fine
