intel/compiler: Fix dynarray usage in intel_clc

The code builds up the dynamic array of objects (spirv_objs) and
collect pointers to each of them into another dynamic
array (spirv_ptr_objs).

If the growth of the first array cause a reallocation, it is
possible that the previous pointers end up invalid.
