utils/unlit: adjust parser to match Report spec
The Haskell 2010 Report says that, for Latex-style Literate format,
"Program code begins on the first line following a line that begins
\begin{code}". (This is unchanged from the 98 Report)
However the unlit.c implementation only matches a line that contains
"\begin{code}" and nothing else. One consequence of this is that one
cannot suffix Latex options to the code environment. I.e., this does
not work:
\begin{code}[label=foo,caption=Foo Code]
Adjust the matcher to conform to the specification from the Report.
The Haskell Wiki currently recommends suffixing a '%' to \begin{code}
in order to deliberately hide a code block from Haskell. This is bad
advice, as it's relying on an implementation quirk rather than specified
behaviour. None-the-less, some people have tried to use it, c.f.
<https://mail.haskell.org/pipermail/haskell-cafe/2009-September/066780.html>
An alternative solution is to define a separate, equivalent Latex
environment to "code", that is functionally identical in Latex but
ignored by unlit. This should not be a burden: users are required to
manually define the code environment anyway, as it is not provided
by the Latex verbatim or lstlistings packages usually used for
presenting code in documents.
Fixes #3549.

Don't let configure perform trivial substitutions (#21846)
Hadrian now performs substitutions, especially to generate .cabal files
from .cabal.in files. Two benefits:
1. We won't have to re-configure when we modify thing.cabal.in. Hadrian
will take care of this for us.
2. It paves the way to allow the same package to be configured
differently by Hadrian in the same session. This will be useful to
fix #19174: we want to build a stage2 cross-compiler for the host
platform and a stage1 compiler for the cross target platform in the
same Hadrian session.

CApiFFI: add ConstPtr for encoding const-qualified pointer return types (#22043)
Previously, when using `capi` calling convention in foreign declarations,
code generator failed to handle const-cualified pointer return types.
This resulted in CC toolchain throwing `-Wincompatible-pointer-types-discards-qualifiers`
warning.
`Foreign.C.Types.ConstPtr` newtype was introduced to handle these cases -
special treatment was put in place to generate appropritetly qualified C
wrapper that no longer triggers the above mentioned warning.
Fixes #22043

Check if the SDoc starts with a single quote (#22488)
This patch fixes pretty-printing of character literals
inside promoted lists and tuples.
When we pretty-print a promoted list or tuple whose first element
starts with a single quote, we want to add a space between the opening
bracket and the element:
'[True] -- ok
'[ 'True] -- ok
'['True] -- not ok
If we don't add the space, we accidentally produce a character
literal '['.
Before this patch, pprSpaceIfPromotedTyCon inspected the type as an AST
and tried to guess if it would be rendered with a single quote. However,
it missed the case when the inner type was itself a character literal:
'[ 'x'] -- ok
'['x'] -- not ok
Instead of adding this particular case, I opted for a more future-proof
solution: check the SDoc directly. This way we can detect if the single
quote is actually there instead of trying to predict it from the AST.
The new function is called spaceIfSingleQuote.

Print unticked promoted data constructors (#20531)
Before this patch, GHC unconditionally printed ticks before promoted
data constructors:
ghci> type T = True -- unticked (user-written)
ghci> :kind! T
T :: Bool
= 'True -- ticked (compiler output)
After this patch, GHC prints ticks only when necessary:
ghci> type F = False -- unticked (user-written)
ghci> :kind! F
F :: Bool
= False -- unticked (compiler output)
ghci> data False -- introduce ambiguity
ghci> :kind! F
F :: Bool
= 'False -- ticked by necessity (compiler output)
The old behavior can be enabled by -fprint-redundant-promotion-ticks.
Summary of changes:
* Rename PrintUnqualified to NamePprCtx
* Add QueryPromotionTick to it
* Consult the GlobalRdrEnv to decide whether to print a tick (see mkPromTick)
* Introduce -fprint-redundant-promotion-ticks

Refactor TyCon to have a top-level product
This patch changes the representation of TyCon so that it has
a top-level product type, with a field that gives the details
(newtype, type family etc), #22458.
Not much change in allocation, but execution seems to be a bit
faster.
