4479427266 ia64: Fix off-by-one bug reported by Todd L Miller.
The rationale for this fix is as follows: for the ALIAS directive, RLEN
specifies the number if instructions for which the region behaves like
the aliased code.  For example, if RLEN=1 then the code follows the
aliased region for 1 instruction and the valid WHEN values should be 0
and 1.  However, with the unpatched code, we would have allowed for -1
and 0, which is wrong.
