nvc0/ir: can't have a join on a load with an indirect source

Browse source 
Triggers an INVALID_OPCODE warning on GK208. Seems rare enough to not
warrant verification on other chips. Fixes the new piglits:

  ubo_array_indexing/fs-nonuniform-control-flow.shader_test
  ubo_array_indexing/vs-nonuniform-control-flow.shader_test
