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.

Tobias Grosser b45ae5601b [ScopDetect] Expand statistics of the detected scops
We now collect:

  Number of total loops
  Number of loops in scops
  Number of scops
  Number of scops with maximal loop depth 1
  Number of scops with maximal loop depth 2
  Number of scops with maximal loop depth 3
  Number of scops with maximal loop depth 4
  Number of scops with maximal loop depth 5
  Number of scops with maximal loop depth 6 and larger
  Number of loops in scops (profitable scops only)
  Number of scops (profitable scops only)
  Number of scops with maximal loop depth 1 (profitable scops only)
  Number of scops with maximal loop depth 2 (profitable scops only)
  Number of scops with maximal loop depth 3 (profitable scops only)
  Number of scops with maximal loop depth 4 (profitable scops only)
  Number of scops with maximal loop depth 5 (profitable scops only)
  Number of scops with maximal loop depth 6 and larger (profitable scops only)

These statistics are certainly completely accurate as we might drop scops
when building up their polyhedral representation, but they should give a good
indication of the number of scops we detect.

Tobias Grosser 5c00b0dc74 [ScopDetectionDiagnostic] Collect statistics for each diagnostic type
Our original statistics were added before we introduced a more fine-grained
diagnostic system, but the granularity of our statistics has never been
increased accordingly. This change introduces now one statistic counter per
diagnostic to enable us to collect fine-grained statistics about who certain
scops are not detected. In case coarser grained statistics are needed, the
user is expected to combine counters manually.

Tobias Grosser 020fa09a3c Remove -polly-code-generator=isl from many test cases
This is the default since a long time. Setting it again does not add value
in any of these test cases.

Tobias Grosser f4ee371e60 tests: Drop -polly-detect-unprofitable and -polly-no-early-exit
These flags are now always passed to all tests and need to be disabled if
not needed. Disabling these flags, rather than passing them to almost all
tests, significantly simplfies our RUN: lines.

Michael Kruse d868b5d509 Merge TempScopInfo into ScopInfo
The TempScopInfo (-polly-analyze-ir) pass is removed and its work taken
over by ScopInfo (-polly-scops). Several tests depend on
-polly-analyze-ir and use -polly-scops instead which for the moment
prints the output of both passes. This again is not expected by some
other tests, especially those with negative searches, which have been
adapted.

Tobias Grosser 173ecab705 Remove target triples from test cases
I just learned that target triples prevent test cases to be run on other
architectures. Polly test cases are until now sufficiently target independent
to not require any target triples. Hence, we drop them.

Tobias Grosser d1e33e7061 ScopDetection: Only detect scops that have at least one read and one write
Scops that only read seem generally uninteresting and scops that only write are
most likely initializations where there is also little to optimize.  To not
waste compile time we bail early.

Johannes Doerfert b164c795b7 [RTC] Runtime Alias Checks for the ISL backend
This change will build all alias groups (minimal/maximal accesses
  to possible aliasing base pointers) we have to check before
  we can assume an alias free environment. It will also use these
  to create Runtime Alias Checks (RTC) in the ISL code generation
  backend, thus allow us to optimize SCoPs despite possibly aliasing
  pointers when this backend is used.

  This feature will be enabled for the isl code generator, e.g.,
  --polly-code-generator=isl, but disabled for:
    - The cloog code generator (still the default).
    - The case delinearization is enabled.
    - The case non-affine accesses are allowed.

Tobias Grosser 50a5e6dac0 test/ScopInfo: Remove %defaultOpts and list passes explicitly
Due to bad habit we sometimes used a variable %defaultOpts that listed
a set of passes commonly run to prepare for Polly. None of these test cases
actually needs special preparation and only two of them need the 'basicaa' to
be scheduled. Scheduling the required alias analysis explicitly makes the test
cases clearer.

Tobias Grosser 7f54714dcc tests: Properly check if asserts are available
In my previous commits I failed to realise that my new requires lines fully
disabled these tests. We now properly check if we are in an asserts build and
only disable the tests if assertions are not available.
