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.

[tests] Force invariant load hoisting for test cases that need it

This will make it easier to switch the default of Polly's invariant load
hoisting strategy and also makes it very clear that these test cases
indeed require invariant code hoisting to work.

Translate SCEVs to isl_pw_aff and their invalid domain

The SCEVAffinator will now produce not only the isl representaiton of
  a SCEV but also the domain under which it is invalid. This is used to
  record possible overflows that can happen in the statement domains in
  the statements invalid domain. The result is that invalid loads have
  an accurate execution contexts with regards to the validity of their
  statements domain. While the SCEVAffinator currently is only taking
  "no-wrapping" assumptions, we can add more withouth worrying about the
  execution context of loads that are optimistically hoisted.
