Secure AVX changes for auditing code.

The original AVX patch used a function pointer to handle the difference
between machines with and without AVX support.  This is insecure.  A
well-placed memory exploit could lead to redirection of the execution.
Using a variable and several tests is a bit slower but cannot be
exploited in this way.
