[committed] reword -Wstrict-aliasing=2 documentation

Subject: [committed] reword -Wstrict-aliasing=2 documentation

The old -Wstrict-aliasing=2 docs said it gave a warning for all aliasing
problems, which is misleading, as we can't give a warning for aliasing
problems we can't detect.  It was only giving a warning for all aliasing
problems that we could detect, even if they were ambiguous.  But rather
than try to define what that means, I just changed it to say that it
detects more cases than -Wstrict-aliasing which is the important point
here.

I tested this with "make info" and "make dvi" on an x86_64-linux
system.  The output looks OK.  I have checked this in.
