I ran clang sanitize=undefined on current perl blead.

Attached is a file containing the failures.  It is in the form of a 
patch (not intended to be applied) of a typical error message from asan 
as a comment preceding the line where the problem occurs in the code.

On #irc, Tony Cook pointed out that probably the integer overflows are 
ok due to our use of -fwrapv.

But I'm creating a ticket for it, so ensure more people look.
