```
spirv: implement pointer comparison in for air cmp

It turns out that the Khronos LLVM SPIRV translator does not support OpPtrEqual.
Therefore, this instruction is emitted using a series of conversions.

This commit breaks intToEnum, because enum was removed from the arithmetic type
info. The enum should be converted to an int before this function is called.
