The combination of ScopedTypeVariables + TypeApplications now no longer
enables the use of type applications in constructor patterns, as per
GHC proposal #448.
This completes the deprecation that begun with GHC 9.8.
We also remove the -Wdeprecated-type-abstractions flag, which was
introduced in GHC 9.10.

In Hadrian, we are careful to use -/- rather than </>, in order to use
/ instead of \ in filepaths. However, this gets ruined by the use of
makeAbsolute from System.Directory, which, on Windows, changes back
forward slashes to backslashes.

Previously the structure of `mmapInRegion` concealed a subtle bug
concerning handling of `mmap` returning mappings below the beginning of
the desired region. Specifically, we would reset `p = result + bytes`
and then again reset `p = region->start` before looping around for
another iteration. This resulted in an infinite loop on FreeBSD.
Fixes #25492.

The 'ModuleGraph' abstraction represents the relationship and strucutre
of the modules being compiled. This structure is meant to be constructed
once at the start of compilation, and never changed again.
However, it's exposed interface was confusing and exposed too many
footguns which led to inneficient usages of the ModuleGraph. This commit
improves significantly the exported interface of ModuleGraph, taking
into consideration the recent improvements around reachability queries.
Since the ModuleGraph graphs and related structures (HPT, EPS) are
performance critical in the sense that somewhat simple mistakes can
cause bad leaks and non-linear memory usage, we want to have proper APIs
that guide efficient usage. This is a good step in that direction.
