ModuleName used to live in GHC.Unit.Module.Name. In this commit, the
definition of ModuleName and its associated functions are moved to
Language.Haskell.Syntax.Module.Name according to the current plan
towards making the AST GHC-independent.
The instances for ModuleName for Outputable, Uniquable and Binary were
moved to the module in which the class is defined because these instances
depend on GHC.
The instance of Eq for ModuleName is slightly changed to no longer
depend on unique explicitly and instead uses FastString's instance of
Eq.

Move the GHC-independent definitions from GHC.Hs.ImpExp to
Language.Haskell.Syntax.ImpExp with the required TTG extension fields
such as to keep the AST independent from GHC.
This is progress towards having the haskell-syntax package, as described
in #21592

Move the definition of HsModule defined in GHC.Hs to

This new flag embeds a lookup table from the address of an info table
to information about that info table.
The main interface for consulting the map is the `lookupIPE` C function
> InfoProvEnt * lookupIPE(StgInfoTable *info)
The `InfoProvEnt` has the following structure:
> typedef struct InfoProv_{
> char * table_name;
> char * closure_desc;
> char * ty_desc;
> char * label;
> char * module;
> char * srcloc;
> } InfoProv;
>
> typedef struct InfoProvEnt_ {
> StgInfoTable * info;
> InfoProv prov;
> struct InfoProvEnt_ *link;
> } InfoProvEnt;
The source positions are approximated in a similar way to the source
positions for DWARF debugging information. They are only approximate but
in our experience provide a good enough hint about where the problem
might be. It is therefore recommended to use this flag in conjunction
with `-g<n>` for more accurate locations.
The lookup table is also emitted into the eventlog when it is available
as it is intended to be used with the `-hi` profiling mode.
Using this flag will significantly increase the size of the resulting
object file but only by a factor of 2-3x in our experience.

FastStrings can be compared in 2 ways: by Unique or lexically. We don't
want to bless one particular way with an "Ord" instance because it leads
to bugs (#18562) or to suboptimal code (e.g. using lexical comparison
while a Unique comparison would suffice).
UTF-8 encoding has the advantage that sorting strings by their encoded
bytes also sorts them by their Unicode code points, without having to
decode the actual code points. BUT GHC uses Modified UTF-8 which
diverges from UTF-8 by encoding \0 as 0xC080 instead of 0x00 (to avoid
null bytes in the middle of a String so that the string can still be
null-terminated). This patch adds a new `utf8CompareShortByteString`
function that performs sorting by bytes but that also takes Modified
UTF-8 into account. It is much more performant than decoding the strings
into [Char] to perform comparisons (which we did in the previous patch).
