llvm.swift.async.context.addr cannot be modeled as NoMem because we don't want it to be cse'd accross async suspends
An async suspend models the split between two partial async functions.
`llvm.swift.async.context.addr ` will have a different value in the two
partial functions so it is not correct to generally CSE the instruction.
