Cleanup related to Visual C++ predefined macros
The attached patch does the following cleanup, mostly related to Visual C++ predefined macros. 1. Do not define _M_AMD64, _M_IA64, and _WIN64 on the compiler command line because these are Visual C++ predefined macros. Note that we don't define _M_IX86 or _WIN32 on the compiler command line. 2. Remove obsolete code for Windows NT Alpha and MIPS. 3. Test the predefined macros (_M_FOO) in addition to the macros defined by <windows.h> (_FOO_). Note: _win95.cfg and _winnt.cfg are NSPR public headers (prcpucfg.h). They may be compiled by the resource compiler (rc.exe), which does not predefine the _M_FOO macros, so _win95.cfg and _winnt.cfg must also test the _FOO_ macros, which our build systems define on the resource compiler command line. On the other hand, _win95.h and _winnt.h are only used by NSPR internally. They are never compiled by the resource compiler. So _win95.h and _winnt.h only need to test the _M_FOO predefined macros. Should we do that to simplify the code?
I checked in the patch on the NSPR trunk (NSPR 4.8.4).
