Adjust naming of Win32/64 and x86/64 words in comments and documentation

* ChangeLog: Replace i386 and X86 to x86; replace x86_64 and amd64 to
x64; replace "Win32 pthreads" to pthreads-win32; lower case win32s,
x86, x64; replace win32 to Win32; replace "MS Windows" to Windows (in
documentation and comments).
