Removed an intermediate list via a fold.
realRegsAlias: Manually inlined the list functions to get better code.
Linear.hs added a bang somewhere.

In which we add a new code generator to the Glasgow Haskell
Compiler. This codegen supports ELF and Mach-O targets, thus covering
Linux, macOS, and BSDs in principle. It was tested only on macOS and
Linux. The NCG follows a similar structure as the other native code
generators we already have, and should therfore be realtively easy to
follow.
It supports most of the features required for a proper native code
generator, but does not claim to be perfect or fully optimised. There
are still opportunities for optimisations.

Move uniqFromMask from Unique.Supply to Unique.
Move the the functions that call mkUnique from Unique to Builtin.Uniques

- put panic related functions into GHC.Utils.Panic
- put trace related functions using DynFlags in GHC.Driver.Ppr
One step closer making Outputable fully independent of DynFlags.

This fixes #17667 and should help to avoid such issues going forward.
The changes are mostly mechanical in nature. With two notable
exceptions.
* The register allocator.
The register allocator references registers by distinct uniques.
However they come from the types of VirtualReg, Reg or Unique in
various places. As a result we sometimes cast the key type of the
map and use functions which operate on the now typed map but take
a raw Unique as actual key. The logic itself has not changed it
just becomes obvious where we do so now.
* <Type>Env Modules.
As an example a ClassEnv is currently queried using the types `Class`,
`Name`, and `TyCon`. This is safe since for a distinct class value all
these expressions give the same unique.
getUnique cls
getUnique (classTyCon cls)
getUnique (className cls)
getUnique (tcName $ classTyCon cls)
This is for the most part contained within the modules defining the
interface. However it requires us to play dirty when we are given a
`Name` to lookup in a `UniqFM Class a` map. But again the logic did
not change and it's for the most part hidden behind the Env Module.
Some of these cases could be avoided by refactoring but this is left
for future work.
We also bump the haddock submodule as it uses UniqFM.
