Guy Blank 0c42d8c35b VX512] Only look at lower bit in constant scalar masks 
for scalar masked instructions only the lower bit of the mask is relevant. so for constant masks we should either do an unmasked operation or no operation, depending on the value of the lower bit.
This patch handles cases where the lower bit is '1'.
