<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">PmCheck: Big refactor of module structure
* Move everything from `GHC.HsToCore.PmCheck.*` to
`GHC.HsToCore.Pmc.*` in analogy to `GHC.Tc`, rename exported
`covCheck*` functions to `pmc*`
* Rename `Pmc.Oracle` to `Pmc.Solver`
* Split off the LYG desugaring and checking steps into their own
modules (`Pmc.Desugar` and `Pmc.Check` respectively)
* Split off a `Pmc.Utils` module with stuff shared by
`Pmc.{,Desugar,Check,Solver}`
* Move `Pmc.Types` to `Pmc.Solver.Types`, add a new `Pmc.Types` module
with all the LYG types, which form the interfaces between
`Pmc.{Desugar,Check,Solver,}`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Extract SharedIdEnv into its own module
It's now named `GHC.Types.Unique.SDFM.UniqSDFM`.
The implementation is more clear about its stated goals and supported
operations.
