Subject: [PATCH] SIMD: disable compile time checks
SSE4.1 support is checked at runtime, so compile time checks are
redundant at best and harmful when compiling for a different machine.
Further more, a logic error prevented the use of SSE4.1 on systems with
any version of AVX available. This is fixed now.
