    temporary hack to test nested conditionals

commit fc38c827716d333c92017348add1e80ea78af948

    Initial implementation of IF/ELSE/ENDIF using conditional masking.
    
    mach->CondMask controls writing to each of the 4 components in a quad.
    mach->CondMaskStack handles nested conditionals.
    Only a few of the micro ops (add/sub/mul/store) have been updated to obey CondMask at this time.
