Rename `cloneBndrs` and such — now all the monadic ones have an `M` suffix.

We now have `cloneBndrs` and `cloneRecIdBndrs` which take a `UniqSupply` argument, and `cloneBndrsM` and `cloneRecIdBndrsM` which rather have a `MonadUnique` constraint.

Use `Infinite` in unique generation, and clean up some other partial uni patterns as well.

Also drop the losing `instance MonadFail UniqSM`.

We redefine `getUniquesM` in terms of `Infinite` rather than `[]`, and define another method `getUniqueListM` for the use sites where we actually want a `[]`.
Thus, at many sites, we can avoid the partiality of the empty list case.

We also define `withUniques`, `withUniquesM`, and `withUniquesM'`, which traverse an arbitrary `Traversable` structure and introduce a `Unique` for each element.
This allows us to redefine various functions to operate on more appropriate types than `[]` and avoid further partiality (in the form of incomplete-uni-patterns).

Use `Infinite` in `GHC.Tc.Deriv.Functor`.

Make the list of variables to use in generated code `Infinite`, to avoid panicking on the (now impossible) empty list case.

Use `Infinite` in `GHC.Runtime.Debugger`.

Make the list of available names `Infinite`, to avoid panicking on the (now impossible) empty list case.

Avoid incomplete-uni-patterns in `GHC.Cmm.DebugBlock`.

We do so by changing the type of `BlockContext` to statically (in GHC) exclude the possibility of Cmm statics, and using `NonEmpty` lists of `BlockContext`s in `cmmDebugGen`.

Avoid incomplete-uni-patterns in `GHC.Types.Literal`.

We do so by introducing `mkLitNumberWrap'` whose ultimate codomain is `Integer` rather than `Literal`, and then use that rather than `mkLitNumberWrap` where we just need the number rather than the `Literal`.

Avoid incomplete-uni-patterns in `GHC.CmmToAsm.X86.CodeGen`.

- Match the vector element list only once in `shuffleInstructions`.
- Define `isSuitableFloatingPointLit_maybe` which returns `Just` the width if the lit is indeed suitable.

Clean up more incomplete uni patterns.

At some sites, we merely panic if the `[]` or `Maybe` is empty when we convert to `NonEmpty` or `Identity`, but at least now we make it explicit.

At other sites, we are able to use more precise types and avoid the partiality altogether. To do so, we redefine various functions to operate over `Traversable` arguments, so we can use the appropriate shape where known.
