Implementations for SSE3 CPUs (prescott)

Instead of fixing some of the bugs with HostCall when paired with vectors, i'll simply remove as many host calls as I can within the most used vector instructions - then just minimize their usage to memory read/writes.
Emitting the raw assembly code is faster than doing a HostCall, HostCalls are VERY expensive. So this is the desired output anyways.

There are bugs related to not having SSE4.1, but those are present on master as well, insofar from my own testing it seems to work just fine
