b5e731dde2 WalkUtils: fix a crash when visiting mismatching types 
The path components may not be related to the current value in case mismatching types are visited, e.g. different concrete types of an existential.
This can lead to mismatching operand numbers for struct and tuple instructions.

1f0f9d65b9 ComputeSideEffects: ignore side effects of debug_value with address operands

e26affacbd ComputeSideEffects: correct side effects for destroy_addr 
A destroy_addr also involves a read from the address. It's equivalent to a `%x = load [take]` and `destroy_value %x`.
It's also a write, because the stored value is not available anymore after the destroy.

Fixes a compiler crash in SILMem2Reg.

d4d1620f28 Swift SIL: rework Instruction and BasicBlock lists to support deleting instructions during iteration 
Replace the generic `List` with the (non-generic) `InstructionList` and `BasicBlockList`.
The `InstructionList` is now a bit different than the `BasicBlockList` because it supports that instructions are deleted while iterating over the list.
Also add a test pass which tests instruction modification while iteration.
