Auto merge of #71044 - ecstatic-morse:body-predecessor-cache, r=oli-obk
Remove `BodyAndCache` ...returning to the original approach using interior mutability within `Body`. This simplifies the API at the cost of some uncontended mutex locks when the parallel compiler is enabled. The current API requires you to either have a mutable reference to `Body` (`&mut BodyAndCache`), or to compute the predecessor graph ahead of time by creating a `ReadOnlyBodyAndCache`. This is not a good fit for, e.g., the dataflow framework, which 1. does not mutate the MIR 2. only sometimes needs the predecessor graph (for backward dataflow problems)
