Someone broke vectorizer testcases on powerpc

[Ira Rosen <IRAR at il dot ibm dot com>]

A lot of the vectorizer testcases are broken on powerpc-linux. The last
version they passed was r119475 (from December 3). The tests are failing at
least since December 6. Looking at the tests that fail, it seems that the
failures are connected to misaligned accesses. Wonder which patch broke
it...
