WIP: debug memxor() test failure

On x86 using GCC 4.8.1, the memxor_aligned test fails when not reading from
"ca" after the last test. Also, the failure occurs only when doing the 16-bit
aligned test before the 8-bit aligned test. So either our inlining memxor()
does something wrong, or something else is screwed.
