1c40579de5 emit_x64_vector: Simplify "position == 0" case for EmitVectorExtract() 
In the event position is zero, we can just treat it as a NOP, given
there's no need to move the data.

e335050886 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.

d895a84e72 emit_x64_floating_point: EmitFPToFixed: maxsd optimization 
maxsd is not required when doing a signed conversion, because x64
