With this PR we don't store the dep-graph as a set of `DepNode<IndexIntoDefIdDirectory>` anymore but instead as a set of `DepNode<DefPathHash>`. Since a `DefPathHash` is a global identifier that is valid across compilation sessions, we don't need the `DefIdDirectory` anymore.
Since a `DepNode<DefPathHash>` is bigger than a `DepNode<IndexIntoDefIdDirectory>` and our on-disk encoding of the dep-graph is inefficient, this PR will probably increase the amount of space the dep-graph takes up on disk. I'm in the process of gathering some performance data.

querify layout and move param env out of the infcx
The main goal of this PR is to move the parameter environment *out* of the inference context. This is because the inference environment will soon be changing over the course of inference --- for example, when we enter into a `for<'a> fn(...)` type, we will push a new environment with an increasing universe index, rather than skolemizing the `'a` references. Similarly, each obligation will soon be able to have a distinct parameter environment, and therefore the `Obligation` struct is extended to carry a `ParamEnv<'tcx>`. (I debated about putting it into the cause; seems plausible, but also weird.)
Along the way, I also reworked how layout works, moving the layout cache into a proper query along the lines of needs-drop and friends.
Finally, tweaks the inference context API. It seemed to be accumulating parameters at an alarming rate. The main way to e.g. make a subtype or equality relationship is to do the following:
infcx.at(cause, param_env).sub(a, b)
infcx.at(cause, param_env).eq(a, b)
In both cases, `a` is considered the "expected" type (this used to be specified by a boolean). I tried hard to preserve the existing notion of what was "expected", although in some cases I'm not convinced it was being set on purpose one way or the other. This is why in some cases you will see me do `sup(b, a)`, which is otherwise equivalent to `sub(a, b)`, but sets the "expected type" differently.
