Work around PowerVR's shader compiler. 

This bug has been reported to IMGTec at https://pvrsupport.imgtec.com/ticket/472

The basic idea of the bug is that if you're doing a bitwise and  of a constant value vector with a constant scalar value, this causes PowerVR's shader
compiler to fail out with a very non-descriptive message.
Working around the issue by making the value a vector that it is being masked by.
