87372917f9 emit_x64_vector: Simplify "position == 0" case for EmitVectorExtractLower() 
In the event position == 0, we can just treat it as a simple movq,
clearing the upper half of the XMM register. This also makes that case
use only one register.

27427595b7 emit_x64_floating_point: EmitFPToFixed: maxsd optimization 
maxsd is not required when doing a signed conversion, because x64
