RFR (small) 6518907: purge IA64 platform-specific ifdefs in source code

[David Holmes]

Notwithstanding we may have to abandon this if the community is using 
the IA64 "support" that exists in the shared code ...

Are the SA changes consistent with what Yumin had proposed and is fixing 
under:

https://jbs.oracle.com/bugs/browse/JDK-8000412

---

This change in the windows code needs closer examination:

-#ifdef _M_IA64
-#define __CPU__ ia64
-#elif _M_AMD64
-#define __CPU__ amd64
-#else
-#define __CPU__ i486
-#endif

while it appears that __CPU__ is not being used in our source code, it 
may be that this was needed to affect other headers and/or the compiler. 
This dates back a long way.

---

There are no makefile changes to remove ia64 settings. If we are going 
to do this then we should do it all.

Cheers,
David
