Michael Kruse 842314b5f0 [Polly] Update isl to isl-0.23-61-g24e8cd12.
This fixes llvm.org/PR48554

Some test cases had to be updated because the hash function for
union_maps have been changed which affects the output order.

Tobias Grosser 8133128c17 [ScopInfo] Do not add array name into memory reference ids
Before this change a memory reference identifier had the form:

  <STMT>_<ACCESSTYPE><ID>_<MEMREF>, e.g., Stmt_bb9_Write0_MemRef_tmp11

After this change, we use the format:

  <STMT>_<ACCESSTYPE><ID>, e.g., Stmt_bb9_Write0

The name of the array that is accessed through a memory reference is not
necessary to uniquely identify a memory reference, but was only added to
provide additional information for debugging. We drop this information now
for the following two reasons:

  1) This shortens the names and consequently improves readability
  2) This removes a second location where we decide on the name of a scop array,
     leaving us only with the location where the actual scop array is created.

Having after 2) only a single location to name scop arrays will allow us to
change the naming convention of scop arrays more easily, which we will do
in a future commit to reduce compilation time.

Michael Kruse 959a8dc39f Update to ISL 0.16.1

Michael Kruse 5a9a65e43f Prepare unit tests for update to ISL 0.16
ISL 0.16 will change how sets are printed which breaks 117 unit tests
that text-compare printed sets. This patch re-formats most of these unit
tests using a script and small manual editing on top of that. When
actually updating ISL, most work is done by just re-running the script
to adapt to the changed output.

Some tests that compare IR and tests with single CHECK-lines that can be
easily updated manually are not included here.

The re-format script will also be committed afterwards. The per-test
formatter invocation command lines options will not be added in the near
future because it is ad hoc and would overwrite the manual edits.
Ideally it also shouldn't be required anymore because ISL's set printing
has become more stable in 0.16.

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.

Tobias Grosser 5fd8c0961e Model fixed-size multi-dimensional arrays if possible multi-dimensional
If the GEP instructions give us enough insights, model scalar accesses as
multi-dimensional (and generate the relevant run-time checks to ensure
correctness). This will allow us to simplify the dependence computation in
a subsequent commit.

Johannes Doerfert 883f8c1d2f Use modulo semantic to generate non-integer-overflow assumptions
This will allow to generate non-wrap assumptions for integer expressions
  that are part of the SCoP. We compare the common isl representation of
  the expression with one computed with modulo semantic. For all parameter
  combinations they are not equal we can have integer overflows.

  The nsw flags are respected when the modulo representation is computed,
  nuw and nw flags are ignored for now.

  In order to not increase compile time to much, the non-wrap assumptions
  are collected in a separate boundary context instead of the assumed
  context. This helps compile time as the boundary context can become
  complex and it is therefor not advised to use it in other operations
  except runtime check generation. However, the assumed context is e.g.,
  used to tighten dependences. While the boundary context might help to
  tighten the assumed context it is doubtful that it will help in practice
  (it does not effect lnt much) as the boundary (or no-wrap assumptions)
  only restrict the very end of the possible value range of parameters.

  PET uses a different approach to compute the no-wrap context, though lnt runs
  have shown that this version performs slightly better for us.

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.

Johannes Doerfert f6557f98a2 Rename the Dependences pass to DependenceInfo [NFC]
We rename the Dependences pass to DependenceInfo as a first step to a
  caching pass policy. The new DependenceInfo pass will later provide
  "Dependences" for a SCoP.

  To keep consistency the test folder is renamed too.
