spirv: handle OpUndef as part of the variable parsing pass
Looking at the following bit of SPIRV shader :
...
%zero = OpConstant %i32 0
%ivec3_0 = OpConstantComposite %ivec3 %zero %zero %zero
%vec3_undef = OpUndef %ivec3
%sc_0 = OpSpecConstant %i32 0
%sc_1 = OpSpecConstant %i32 0
%sc_2 = OpSpecConstant %i32 0
...
Our compiler currently stops parsing variables & types on the OpUndef
and switches to instructions, leaving the following sc_[0-2] variables
untreated.
