PR tree-optimization/36206
* tree-scalar-evolution.c: Remove enum INSERT_SUPERLOOP_CHRECS,
FOLD_CONVERSIONS.
(instantiate_scev_1): Rename flags to fold_conversions.
Do not check for INSERT_SUPERLOOP_CHRECS, keep SSA_NAMEs defined
outeside instantiation_loop.
* tree-chrec.h (evolution_function_is_affine_in_loop): New.
(evolution_function_is_affine_or_constant_p): Removed.
* tree-data-ref.c (dr_analyze_indices): Replace resolve_mixers with
instantiate_scev.
(analyze_siv_subscript): Pass in the loop nest number.
Call evolution_function_is_affine_in_loop instead of
evolution_function_is_affine_p.
(analyze_overlapping_iterations): Pass in the loop nest number.
* tree-chrec.h (chrec_fold_op): New.
* tree-data-ref.c (initialize_matrix_A): Traverse NOP_EXPR, PLUS_EXPR, and
other trees.
* testsuite/gfortran.dg/pr36206.f: New.
