Maybe we should just not use the gcc intrinsics headers and use asm blocks
instead.

If using the intrinsics headers requires you to compile with -msse and the
like, this is IMHO a bug in gcc though. We are intentionally not compiling with
-msse as this would compile the C code into something that does not run without
SSE (possibly, at least it allows gcc to emit SSE opcodes everywhere). We only
want to have these specific parts of the code using SSE, and then detect at
runtime if the CPU supports SSE and otherwise never call it.
