rts/CNF: Fix fixup comparison function
Previously we would implicitly convert the difference between two words
to an int, resulting in an integer overflow on 64-bit machines.
Fixes #16992

Pack some of IdInfo fields into a bit field
This reduces residency of compiler quite a bit on some programs.
Example stats when building T10370:
Before:
2,871,242,832 bytes allocated in the heap
4,693,328,008 bytes copied during GC
33,941,448 bytes maximum residency (276 sample(s))
375,976 bytes maximum slop
83 MiB total memory in use (0 MB lost due to fragmentation)
After:
2,858,897,344 bytes allocated in the heap
4,629,255,440 bytes copied during GC
32,616,624 bytes maximum residency (278 sample(s))
314,400 bytes maximum slop
80 MiB total memory in use (0 MB lost due to fragmentation)
So -3.9% residency, -1.3% bytes copied and -0.4% allocations.
Fixes #17497
Metric Decrease:

T9675

Add few cleanups of the CAF logic

CprAnal: Don't attach CPR sigs to expandable bindings (#18154)
Instead, look through expandable unfoldings in `cprTransform`.
See the new Note [CPR for expandable unfoldings]:
```
Long static data structures (whether top-level or not) like
xs = x1 : xs1
xs1 = x2 : xs2
xs2 = x3 : xs3
should not get CPR signatures, because they
* Never get WW'd, so their CPR signature should be irrelevant after analysis
(in fact the signature might even be harmful for that reason)
* Would need to be inlined/expanded to see their constructed product
* Recording CPR on them blows up interface file sizes and is redundant with
their unfolding. In case of Nested CPR, this blow-up can be quadratic!
But we can't just stop giving DataCon application bindings the CPR property,
for example
fac 0 = 1
fac n = n * fac (n-1)
fac certainly has the CPR property and should be WW'd! But FloatOut will
transform the first clause to
lvl = 1
fac 0 = lvl
If lvl doesn't have the CPR property, fac won't either. But lvl doesn't have a
CPR signature to extrapolate into a CPR transformer ('cprTransform'). So
instead we keep on cprAnal'ing through *expandable* unfoldings for these arity
0 bindings via 'cprExpandUnfolding_maybe'.
In practice, GHC generates a lot of (nested) TyCon and KindRep bindings, one
for each data declaration. It's wasteful to attach CPR signatures to each of
them (and intractable in case of Nested CPR).
```
Fixes #18154.

Don't reload environment files on every setSessionDynFlags
Makes `interpretPackageEnv` (which loads envirinment files) a part of
`parseDynamicFlags` (parsing command-line arguments, which is typically
done once) instead of `setSessionDynFlags` (which is typically called
several times). Making several (transitive) calls to `interpretPackageEnv`,
as before, caused #18125 #16318, which should be fixed now.

Factor out HsPatSigType for pat sigs/RULE term sigs (#16762)
This implements chunks (2) and (3) of
https://gitlab.haskell.org/ghc/ghc/issues/16762#note_270170. Namely,
it introduces a dedicated `HsPatSigType` AST type, which represents
the types that can appear in pattern signatures and term-level `RULE`
binders. Previously, these were represented with `LHsSigWcType`.
Although `LHsSigWcType` is isomorphic to `HsPatSigType`, the intended
semantics of the two types are slightly different, as evidenced by
the fact that they have different code paths in the renamer and
typechecker.
See also the new `Note [Pattern signature binders and scoping]` in
`GHC.Hs.Types`.

Tweak man page for ghc command
This commit updates the ghc command's man page as followings:
* Enable `man_show_urls` to show URL addresses in the `DESCRIPTION`
section of ghc.rst, because sphinx currently removes hyperlinks
for man pages.
* Add a `SEE ALSO` section to point to the GHC homepage
