spirv-opt: performance pass breaks task/mesh shader taskNV data #3673

Getting errors as follows for data that is passed via taskNV from task to mesh shader in both mesh and task shader stage.

// example task shader output
taskNV out Task { uint base; uint8_t subIDs[32] } OUT;

// example mesh shader input
taskNV in Task { uint base; uint8_t subIDs[32] } IN;

by spec definition location assignment is not required for taskNV qualified data between task/mesh

shaderc: internal error: compilation succeeded but failed to optimize: Member index 0 is missing a location assignment
