base: Eliminate module reexport in GHC.Exception

The metric increase here isn't strictly due to this commit but it's a
rather small, incidental change.

Metric Increase:
    T8095
    T13386

Metric Decrease:
    T8095
    T13386
    T18304

base: Add disclaimers in internal modules

To warn users that these modules are internal and their interfaces may
change with little warning.

As proposed in Core Libraries Committee #146 [CLC146].

Bump Cabal submodule

We need to bump the Cabal submodule to include commit ec75950
which fixes an issue with a dodgy import Rep(..) which relied
on GHC bug #23570

Be more eager in TyCon boot validity checking

This commit performs boot-file consistency checking for TyCons into
checkValidTyCl. This ensures that we eagerly catch any mismatches,
which prevents the compiler from seeing these inconsistencies and
panicking as a result.

See Note [TyCon boot consistency checking] in GHC.Tc.TyCl.

Fixes #16127

Refactor estimation of stack info table provenance

This commit greatly refactors the way we compute estimated provenance for stack
info tables. Previously, this process was done using an entirely separate traversal
of the whole Cmm code stream to build the map from info tables to source locations.
The separate traversal is now fused with the Cmm code generation pipeline in
GHC.Driver.Main.

This results in very significant code generation speed ups when -finfo-table-map is
enabled. In testing, this patch reduces code generation times by almost 30% with
-finfo-table-map and -O0, and 60% with -finfo-table-map and -O1 or -O2 .

Fixes #23103

Add a test checking overhead of -finfo-table-map

We want to make sure we don't end up with poor codegen performance resulting from
-finfo-table-map again as in #23103. This test adds a performance test tracking
total allocations while compiling ExactPrint with -finfo-table-map.
