uniform Ptr (UPtr) is a sub class of Ptr
A pointer for a Uniform (UPtr) is a sub type of a Ptr. Everywhere you
can use a Ptr a UPtr will work, but you can't use Ptr where you need
a UPtr. All the UPtr instructions uniformF, gather32, etc are expected
to be hoisted and therefore loaded only once. While the varyings
instructions like load32, etc. are expected to remain in the body
of the loop, and be evaluated each time through the loop.
