wordsize.h for x86-64

I'd like to follow the example of Sparc in using __WORDSIZE in the
glibc headers of x86-64 to allow compilation with both 32-bit and
64-bit compilers of the same headers.

Since this first appended patch affects also i386, I'd like to get
permission to commit this file to both branches.

	* sysdeps/i386/bits/wordsize.h: New file to allow sharing with
	x86-64.
	* sysdeps/x86_64/bits/wordsize.h: Likewise.
