Confirmed, if this patch is not accepted for 3.4, there is no need for it for 3.5 (for tree-ssa) as the
testcase is optimized already at the tree level where you do not have the problems of the register
sizes.

tree-ssa fixes the small test case. But the large file in vortex still fails. This patch is still needed
and a revised versionb is being reviewed at this time.
