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. Reported-by: Sean Silva <silvas@purdue.edu> llvm-svn: 176900

[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. llvm-svn: 218046
