Deprecate lnat, and use StgWord instead

lnat was originally "long unsigned int" but we were using it when we
wanted a 64-bit type on a 64-bit machine.  This broke on Windows x64,
where long == int == 32 bits.  Using types of unspecified size is bad,
but what we really wanted was a type with N bits on an N-bit machine.
StgWord is exactly that.

lnat was mentioned in some APIs that clients might be using
(e.g. StackOverflowHook()), so we leave it defined but with a comment
to say that it's deprecated.
