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.
