Lioncache 30cb1aaaed IR: Add VPCMPESTRX fallback ...

In order to implement the SSE4.2 string instructions in a reasonable
manner, we can make use of a fallback implementation for the time
being.

This implementation just returns the intermediate result and leaves it
up to the function making use of it to derive the final result from said
intermediate result. This is fine, considering we have the immediate
control byte that tells us exactly what is desired as far as output
formats go.

Given that the result of this IR op will never take up more than
16-bits, we store the flags we need to set in the upper 16 bits of the
result to avoid needing to implement multiple return values in the JIT.

Also, since the IR op just returns the intermediate result, this can be
used to implement all of the explicit string instructions with a single IR op.

The implementation is pretty heavily documented to help make heads or
tails of these monster instructions.
