Update to splay-tree.h for 64-bit Windows host

[Nick Clifton <nickc@redhat.com>]

Hi Guys,

  I have checked in the patch below as part of a wider patch to allow
  the binutils to be built on a 64-bit windows host.  It provides a
  64-bit windows alternative for the type of the splay_tree_key and
  splay_tree_value types.

Cheers
  Nick

	* splay-tree.h (libi_uhostptr_t, libi_shostptr_t): New types,
	needed for WIN64 when a long is not wide enough for a pointer.
        (splay_tree_key, splay_tree_value): Use the new types.
