Fix small bug traversing users in interface_var_sroa (#4850) 
Fix code that is traversing def-use user structure at the same time
that it is changing it. This is dicey at best and error prone at worst.
This was uncovered making a change to the id_to_user representation.

spirv-opt: add pass for interface variable scalar replacement (#4779) 
Replace shader's stage variables whose types are array or matrix
with scalars/vectors.
For example,
```
Before:
  %foo = OpVariable %_ptr_Output__arr_v2float_uint_4 Output
After:
  %foo = OpVariable %_ptr_Output_v2float Output
  %foo_0 = OpVariable %_ptr_Output_v2float Output
  %foo_1 = OpVariable %_ptr_Output_v2float Output
  %foo_2 = OpVariable %_ptr_Output_v2float Output
```
