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 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 7ceb040213 Add early exits for SCoPs we did not optimize
This allows us to skip ast and code generation if we did not optimize
  a SCoP and will not generate parallel or alias annotations. The
  initial heuristic to exit is simple but allows improvements later on.

  All failing test cases have been modified to disable early exit, thus
  to keep their coverage.

Johannes Doerfert 305fed96e6 Drop Cloog support
This commit drops the Cloog support for Polly. The scripts and
  documentation are changed to only use isl as prerequisity. In the code
  all Cloog specific parts have been removed and all relevant tests have
  been ported to the isl backend when it was created.

Tobias Grosser 2faa569c0a Replace %defaultOpts with explicit pass names
This replaces the use of %defaultOpts = '-basicaa -polly-prepare' with the
minimal set of passes necessary for a test to succeed. Of the test cases that
previously used %defaultOpts 76 test cases require none of these passes, 42
need -basicaa and only 2 need -polly-prepare. Our change makes this requirement
explicit.

In Polly many test cases have been using a macro '%defaultOpts' which run a
couple of preparing passes before the actual Polly test case. This macro was
introduced very early in the development of Polly and originally contained a
large set of canonicalization passes.  However, as the need for additional
canonicalization passes makes test cases harder to understand and also more
fragile in terms of changes in such passes, we aim since a longer time to only
include the minimal set of passes necessary. This patch removes the last
leftovers from of %defaultOpts and brings our tests cases more in line to what
is usus in LLVM itself.
