Michael Kruse 5c02808131 [polly] Introduce -polly-print-* passes to replace -analyze. 
The `opt -analyze` option only works with the legacy pass manager and might be removed in the future, as explained in llvm.org/PR53733. This patch introduced -polly-print-* passes that print what the pass would print with the `-analyze` option and replaces all uses of `-analyze` in the regression tests.

There are two exceptions: `CodeGen\single_loop_param_less_equal.ll` and `CodeGen\loop_with_condition_nested.ll` use `-analyze on the `-loops` pass which is not part of Polly.

Johannes Doerfert af3e301a67 [FIX] Restructure invariant load equivalence classes 
Sorting is replaced by a demand driven code generation that will pre-load a
  value when it is needed or, if it was not needed before, at some point
  determined by the order of invariant accesses in the program. Only in very
  little cases this demand driven pre-loading will kick in, though it will
  prevent us from generating faulty code. An example where it is needed is
  shown in:
    test/ScopInfo/invariant_loads_complicated_dependences.ll

  Invariant loads that appear in parameters but are not on the top-level (e.g.,
  the parameter is not a SCEVUnknown) will now be treated correctly.

Tobias Grosser e2c8275346 ScopInfo: Allow simple 'AddRec * Parameter' products in delinearization 
We also allow such products for cases where 'Parameter' is loaded within the
scop, but where we can dynamically verify that the value of 'Parameter' remains
unchanged during the execution of the scop.

This change relies on Polly's new RequiredILS tracking infrastructure recently
contributed by Johannes.
