[Bug target/32893] zlib segfault in inflate_table() compiled w/ -O -msse2 ftree-vectorize

Ryan, I wonder what happens if you force alignment in the source code, like so:

unsigned short count[MAXBITS+1] __attribute__ ((__aligned__(16))) ;    

In this case the vectorizer does not change the alignment of the array. I
wonder if the compiler honors the alignment attribute when the user asks for
it, rather than the vectorizer.
