c829d5bd77 SimplifyBeginCOWMutation: don't eliminate end_cow_mutation instructions with the [keep_unique] flag 
This flag is important for following optimizations. Therefore such `end_cow_mutation` instructions must not be removed.
Also, keep the flag in a SILCombine transformation.

eea471fe99 add the ComputeEffects pass 
The ComputeEffects pass derives escape information for function arguments and adds those effects in the function.
This needs a lot of changes in check-lines in the tests, because the effects are printed in SIL

8e83d5f6e5 tests: add an test to check the optimization result of a reverse-array function. 
This is an end-to-end test to check if the optimization improvements of the previous commits result in good code generation for this function.
