- While an opaque borrow access occurs to part of a value, the entire scope of the access needs to be treated as a liveness range, so add the `EndAccess`es to the liveness range. - The SIL verifier may crash the compiler on SILGen-generated code when the developer's source contains consume-during-borrow code patterns. Allow `load_borrow` instructions to be marked `[unchecked]`, which suppresses verifier checks until the move checker runs and gets a chance to properly diagnose these errors. Fixes rdar://124360175.
