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. llvm-svn: 216815
