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.

This patch addresses:
- A new function pass to compute polyhedral dependences. This is
required to avoid the region pass manager.
- Stores a map of Scop to Dependence object for all the scops present
in a function. By default, access wise dependences are stored.

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.

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.

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.

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.
