Files to repro the problem

Doing:

spirv-cross generated_0.opt.spv --output temp.frag && glslangValidator temp.frag

gives:

temp.frag
ERROR: 0:316: '_6675' : undeclared identifier 
ERROR: 0:316: 'assign' :  cannot convert from ' temp float' to ' temp highp 2-component vector of float'
ERROR: 0:316: '' : compilation terminated 
ERROR: 3 compilation errors.  No code generated.

Found via GraphicsFuzz on spirv-cross git commit 4ce04480.
