Erik Eckstein	eed8645610	Optimizer: improve the load-copy-to-borrow optimization and implement it in swift ... The optimization replaces a `load [copy]` with a `load_borrow` if possible. ``` %1 = load [copy] %0 // no writes to %0 destroy_value %1 ``` -> ``` %1 = load_borrow %0 // no writes to %0 end_borrow %1 ``` The new implementation uses alias-analysis (instead of a simple def-use walk), which is much more powerful. rdar://115315849	2024-10-11 09:41:37 +02:00
