Add an operation `System.IO.hGetNewlineMode`
This commit also contains some small code and documentation changes for
related operations, for the sake of consistency.

rts: opportunistically reclaim slop space in shrinkMutableByteArray#
Previously, `shrinkMutableByteArray#` shrinks a `MutableByteArray#`
in-place by assigning the new size to it, and zeroing the extra slop
space. That slop space is not reclaimed and wasted. But it's often the
case that we allocate a `MutableByteArray#` upfront, then shrink it
shortly after, so the `MutableByteArray#` closure sits right at the
end of a nursery block; this patch identifies such chances, and also
shrink `bd->free` if possible, reducing heap space fragmentation.

Decoupling Language.Haskell.Syntax.Binds from GHC.Types.Basic by transfering InlinePragma types between the modules.
* Moved InlinePragma data-types to Language.Haskell.Syntax.Binds.InlinePragma
* Partitioned of Arity type synonyms to GHC.Types.Arity
* InlinePragma is now extensible via Trees That Grow
* Activation is now extensible via Trees That Grow
* Maybe Arity change to more descriptive InlineSaturation data-type
* InlineSaturation information removed from InlinePragma during GHS parsing pass
* Cleaned up the exposed module interfaces of the new modules
