Stanislav Mekhanoshin 0bf4d71d50 Correct register pressure calculation in presence of subregs 
If a subreg is used in an instruction it counts as a whole superreg
for the purpose of register pressure calculation. This patch corrects
improper register pressure calculation by examining operand's lane mask.
