d535ef006d85dbdb7cda2b09c5bc35cb80108909 allowed the use of up to 10
vanilla registers but didn't update LLVM backend to support them. This
patch fixes it.

* Remove several uses of `sdocWithDynFlags`, especially in GHC.Llvm.*
* Add LlvmOpts datatype to store Llvm backend options
* Remove Outputable instances (for LlvmVar, LlvmLit, LlvmStatic and
Llvm.MetaExpr) which require LlvmOpts.
* Rename ppMetaExpr into ppMetaAnnotExpr (pprMetaExpr is now used in place of `ppr :: MetaExpr -> SDoc`)

This updates comments only.
This patch replaces leaf module names according to new module
hierarchy [1][2] as followings:
* Expand leaf names to easily find the module path:
for instance, `Id.hs` to `GHC.Types.Id`.
* Modify leaf names according to new module hierarchy:
for instance, `Convert.hs` to `GHC.ThToHs`.
* Fix typo:
for instance, `GHC.Core.TyCo.Rep.hs` to `GHC.Core.TyCo.Rep`

Avoid removing some functions that are part of an API even
though they're not used in-tree at the moment.

If `-dppr-debug` is set, then PprUser and PprDump styles are silently
replaced with PprDebug style. This was done in `mkUserStyle` and
`mkDumpStyle` smart constructors. As a consequence they needed a
DynFlags parameter.
Now we keep the original PprUser and PprDump styles until they are used
to create an `SDocContext`. I.e. the substitution is only performed in
`initSDocContext`.

* replace `DynFlags` parameters with `SDocContext` parameters for a few
Ppr related functions: `bufLeftRenderSDoc`, `printSDoc`,
`printSDocLn`, `showSDocOneLine`.
* remove the use of `pprCols :: DynFlags -> Int` in Outputable. We
already have the information via `sdocLineLength :: SDocContext ->
Int`

In !2959 we noticed that there was some redundant code (in GHC.Cmm.Utils
and GHC.Cmm.StgToCmm.Utils) used to deal with `CmmStatics` datatype
(before SRT generation) and `RawCmmStatics` datatype (after SRT
generation).
This patch removes this redundant code by using a single GADT for
(Raw)CmmStatics.

Move handling of big literal strings from CmmToAsm to StgToCmm. It
avoids the use of `sdocWithDynFlags` (cf #10143). We might need to move
this handling even higher in the pipeline in the future (cf #17960):
this patch will make it easier.

Consider
```hs
data T = A | B | C
f :: T -> Int
f A = 1
f x = case x of
A -> 2
B -> 3
C -> 4
```
Clearly, the RHS returning 2 is redundant. But we don't currently see
that, because our approximation to the covered set of the inner case
expression just picks up the positive information from surrounding
pattern matches. It lacks the context sensivity that `x` can't be `A`
anymore!
Therefore, we adopt the conceptually and practically superior approach
of reusing the covered set of a particular GRHS from an outer pattern
match. In this case, we begin checking the `case` expression with the
covered set of `f`s second clause, which encodes the information that
`x` can't be `A` anymore. After this MR, we will successfully warn about
the RHS returning 2 being redundant.
Perhaps surprisingly, this was a great simplification to the code of
both the coverage checker and the desugarer.
Found a redundant case alternative in `unix` submodule, so we have to
bump it with a fix.

Remove several uses of `sdocWithDynFlags`. The remaining ones are mostly
CodeGen related (e.g. depend on target platform constants) and will be
fixed separately.
