Louis Dionne	ceff0b7258	[libc++] Do not require movability in __non_propagating_cache::__emplace_deref ... As explained in http://eel.is/c++draft/range.nonprop.cache#note-1, we should allow copy and move elision to happen when calling emplace_deref in non-propagating-cache. Before this change, the only way to emplace into the non-propagating-cache was to call `__set(*it)`, which materialized `*it` when binding it to the reference argument of `__set` and disabled move elision. As a fly-by change, this also renames `__set` to `__emplace` for consistency and adds tests for it. Differential Revision: https://reviews.llvm.org/D107932	2021-08-17 11:32:40 -04:00
