Ok; but that also means that if you optimize any code you need to make
sure that the "optimizations" are actually appropriate for the CPU
you're running on.
I think the idea of -xbuiltin (someone else mentioned) is better --
compiler generated inlines will probably save more than just the logic
associated with alignment checks, but also function call overhead -- at
least for small strings.
