AK: Move taint_for_optimizer to StdLibExtras.h

Browse source 
Additionally, split it into two versions (for IsIntegral<T> -- asking
to place value into register and for !IsIntegral<T> -- asking to place
value into memory with memory clobber), so that Clang is no more
completely confused about `taint_for_optimizer(AK::StringView&)`.
