Extended Description

Created an attachment (id=460)
testcase to replicate
When compiling sac/testsuite/optimizations/ls/mat.sac, constantfolding creates the following selection operations:
  _ls_282 = _sel_VxA_( [ 1 ], _flat_6);
  _ls_283 = _sel_VxA_( [ 0 ], _flat_6);
  _ls_284 = _sel_VxA_( [ 1 ], _flat_3);
  _ls_285 = _sel_VxA_( [ 0 ], _flat_3);
Again, the index-vectors need to be flattened out, as we only allow scalar constants or identifiers as arguments to primitive functions.
