86ed2295c0 Two fixes:
1. Allow building of Intrinsics.gen to work for srcdir != objdir
2. Add a rule for installation of Intrinsics.gen.

db35180b27 For each loop, keep track of all the IV expressions inserted indexed by
stride. For a set of uses of the IV of a stride which is a multiple
of another stride, do not insert a new IV expression. Rather, reuse the
previous IV and rewrite the uses as uses of IV expression multiplied by
the factor.

e.g.
x = 0 ...; x ++
y = 0 ...; y += 4
then use of y can be rewritten as use of 4*x for x86.
