Proposed fix

Indeed, the users of build_ref_for_offset in ipa-prop.c and ipa-cp.c
do not unshare the base expressions they should.  I have looked at all
other users and found that they either pass declarations or do their
own unsharing and so decided to move the unsharing to
build_ref_for_offset itself.  The attached patch fixes the ICE when
compiling the testcase, I am currently bootstrapping it.
