<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Enable large address space optimization on windows.
Starting with Win 8.1/Server 2012 windows no longer preallocates
page tables for reserverd memory eagerly, which prevented us from
using this approach in the past.
We also try to allocate the heap high in the memory space.
Hopefully this makes it easier to allocate things in the low
4GB of memory that need to be there. Like jump islands for the
linker.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">In `:break ident` allow out of scope and nested identifiers (Fix #3000)
This patch fixes the bug and implements the feature request of #3000.
1. If `Module` is a real module name and `identifier` a name of a
top-level function in `Module` then `:break Module.identifer` works
also for an `identifier` that is out of scope.
2. Extend the syntax for `:break identifier` to:
:break [ModQual.]topLevelIdent[.nestedIdent]...[.nestedIdent]
`ModQual` is optional and is either the effective name of a module or
the local alias of a qualified import statement.
`topLevelIdent` is the name of a top level function in the module
referenced by `ModQual`.
`nestedIdent` is optional and the name of a function nested in a let or
where clause inside the previously mentioned function `nestedIdent` or
`topLevelIdent`.
If `ModQual` is a module name, then `topLevelIdent` can be any top level
identifier in this module. If `ModQual` is missing or a local alias of a
qualified import, then `topLevelIdent` must be in scope.
Breakpoints can be set on arbitrarily deeply nested functions, but the
whole chain of nested function names must be specified.
3. To support the new functionality rewrite the code to tab complete `:break`.

Consider the Literal `[256] :: [Data.Word.Word8]`
When the `OverloadedLists` extension is not active, then the `ol_ext` field
in the `OverLitTc` record that is passed to the function `getIntegralLit`
contains the type `Word8`. This is a simple type, and we can use its
type constructor immediately for the `warnAboutOverflowedLiterals` function.
When the `OverloadedLists` extension is active, then the `ol_ext` field
contains the type family `Item [Word8]`. The function `nomaliseType` is used
to convert it to the needed type `Word8`.

<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">rts/Hash: Simplify freeing of HashListChunks
While looking at #18348 I noticed that the treatment of HashLists are a
bit more complex than necessary (which lead to some initial confusion on
my part). Specifically, we allocate HashLists in chunks. Each chunk
allocation makes two allocations: one for the chunk itself and one for a
HashListChunk to link together the chunks for the purposes of freeing.
Simplify this (and hopefully make the relationship between these
clearer) but allocating the HashLists and HashListChunk in a single
malloc. This will both make the implementation easier to follow and
reduce C heap fragmentation.
Note that even after this patch we fail to bound the size of the free
HashList pool. However, this is a separate bug.

This MR makes the UM monad in GHC.Core.Unify into a one-shot
monad. See the long Note [The one-shot state monad trick].
See also #18202 and !3309, which applies this to all Reader/State-like
monads in GHC for compile-time perf improvements. The pattern used
here enables something similar to the state-hack, but is applicable to
user-defined monads, not just `IO`.
