StgToCmm: remove CallOpts in StgToCmm.Closure
StgToCmm: remove dynflag references
StgToCmm: PtrOpts removed
StgToCmm: add TMap to config, Prof - dynflags
StgToCmm: add omit yields to config
StgToCmm.ExtCode: remove redundant import
StgToCmm.Heap: remove references to dynflags
StgToCmm: codeGen api change, DynFlags -> Config
StgToCmm: remove dynflags in Env and StgToCmm
StgToCmm.DataCon: remove dynflags references
StgToCmm: remove dynflag references in DataCon
StgToCmm: add backend avx flags to config
StgToCmm.Prim: remove dynflag references
StgToCmm.Expr: remove dynflag references
StgToCmm.Bind: remove references to dynflags
StgToCmm: move DoAlignSanitisation to Cmm.Type
StgToCmm: remove PtrOpts in Cmm.Parser.y
DynFlags: update ipInitCode api
StgToCmm: Config Module is single source of truth
StgToCmm: Lazy config breaks IORef deadlock
testsuite: bump countdeps threshold
StgToCmm.Config: strictify fields except UpdFrame
Strictifying UpdFrameOffset causes the RTS build with stage1 to
deadlock. Additionally, before the deadlock performance of the RTS
is noticeably slower.
StgToCmm.Config: add field descriptions
StgToCmm: revert strictify on Module in config
testsuite: update CountDeps tests
StgToCmm: update comment, fix exports
Specifically update comment about loopification passed into dynflags
then stored into stgToCmmConfig. And remove getDynFlags from
Monad.hs exports
Types.Name: add pprFullName function
StgToCmm.Ticky: use pprFullname, fixup ExtCode imports
Cmm.Info: revert cmmGetClosureType removal
StgToCmm.Bind: use pprFullName, Config update comments
StgToCmm: update closureDescription api
StgToCmm: SAT altHeapCheck
StgToCmm: default render for Info table, ticky
Use default rendering contexts for info table and ticky ticky, which should be independent of command line input.
testsuite: bump count deps
pprFullName: flag for ticky vs normal style output
convertInfoProvMap: remove unused parameter
StgToCmm.Config: add backend flags to config
StgToCmm.Config: remove Backend from Config
StgToCmm.Prim: refactor Backend call sites
StgToCmm.Prim: remove redundant imports
StgToCmm.Config: refactor vec compatibility check
StgToCmm.Config: add allowQuotRem2 flag
StgToCmm.Ticky: print internal names with parens
StgToCmm.Bind: dispatch ppr based on externality
StgToCmm: Add pprTickyname, Fix ticky naming
Accidently removed the ctx for ticky SDoc output. The only relevant flag
is sdocPprDebug which was accidental set to False due to using
defaultSDocContext without altering the flag.
StgToCmm: remove stateful fields in config
fixup: config: remove redundant imports
StgToCmm: move Sequel type to its own module
StgToCmm: proliferate getCallMethod updated api
StgToCmm.Monad: add FCodeState to Monad Api
StgToCmm: add second reader monad to FCode
fixup: Prim.hs: missed a merge conflict
fixup: Match countDeps tests to HEAD
StgToCmm.Monad: withState -> withCgState
To disambiguate it from mtl withState. This withState shouldn't be
returning the new state as a value. However, fixing this means tackling
the knot tying in CgState and so is very difficult since it changes when
the thunk of the knot is forced which either leads to deadlock or to
compiler panic.

Platform constant wrappers took a DynFlags parameter, hence implicitly
used the target platform constants. We removed them to allow support
for several platforms at once (#14335) and to avoid having to pass
the full DynFlags to every function (#17957).

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.

* use UnitId instead of String to identify wired-in units
* use UnitId instead of Unit in the backend (Unit are only use by
Backpack to produce type-checked interfaces, not real code)
* rename lookup functions for consistency

Introduce GHC.Unit.* hierarchy for everything concerning units, packages
and modules.

Over the years the unit management code has been modified a lot to keep
up with changes in Cabal (e.g. support for several library components in
the same package), to integrate BackPack, etc. I found it very hard to
understand as the terminology wasn't consistent, was referring to past
concepts, etc.
The terminology is now explained as clearly as I could in the Note
"About Units" and the code is refactored to reflect it.
-------------------
Many names were misleading: UnitId is not an Id but could be a virtual
unit (an indefinite one instantiated on the fly), IndefUnitId
constructor may contain a definite instantiated unit, etc.
* Rename IndefUnitId into InstantiatedUnit
* Rename IndefModule into InstantiatedModule
* Rename UnitId type into Unit
* Rename IndefiniteUnitId constructor into VirtUnit
* Rename DefiniteUnitId constructor into RealUnit
* Rename packageConfigId into mkUnit
* Rename getPackageDetails into unsafeGetUnitInfo
* Rename InstalledUnitId into UnitId
Remove references to misleading ComponentId: a ComponentId is just an
indefinite unit-id to be instantiated.
* Rename ComponentId into IndefUnitId
* Rename ComponentDetails into UnitPprInfo
* Fix display of UnitPprInfo with empty version: this is now used for
units dynamically generated by BackPack
Generalize several types (Module, Unit, etc.) so that they can be used
with different unit identifier types: UnitKey, UnitId, Unit, etc.
* GenModule: Module, InstantiatedModule and InstalledModule are now
instances of this type
* Generalize DefUnitId, IndefUnitId, Unit, InstantiatedUnit,
PackageDatabase
Replace BackPack fake "hole" UnitId by a proper HoleUnit constructor.
Add basic support for UnitKey. They should be used more in the future to
avoid mixing them up with UnitId as we do now.
Add many comments.

Add StgToCmm module hierarchy. Platform modules that are used in several
other places (NCG, LLVM codegen, Cmm transformations) are put into
GHC.Platform.
